  • Observation of Current-Induced Lattice Distortion in Spin–Orbit Coupled Iridium Oxide Ca5Ir3O12

    We report current-induced lattice distortion in iridium oxide Ca5Ir3O12 with a hexagonal structure that exhibits nonlinear conductivity along the c-axis. Using the synchrotron radiation X-ray diffraction experiments on the single crystal, the change in the lattice constant due to thermal expansion at temperatures above room temperature and the change in the lattice constant due to the application of current along the c-axis were investigated. We found that the current application along the c-axis caused anisotropic lattice distortion that expanded within the c-plane direction. These results show that the change in the lattice constant ratio a/c due to the application of current is greater than the change in thermal expansion caused by self-heating. In spin–orbit coupled oxides, this result reveals the possibility of significant current-induced distortion based on a mechanism different from the conventional piezoelectric effect.

    Hybrid halide perovskite research has recently been focused on thermoelectric energy harvesting due to the cost-effectiveness of the fabrication approach and to the ultra-low thermal conductivity. To achieve high performance, tuning of the electrical conductivity is a key parameter that is influenced by grain boundary scattering and charge carrier density. The fabrication process allows the tuning of these parameters. We report the use of anti-solvent to enhance the thermoelectric performance of lead-free hybrid halide perovskite (CH3NH3SnI3) thin films. Thin films with anti-solvent show higher connectivity in grains and higher Sn+4 oxidation states which result in the enhancement of the value of electrical conductivity. The thin films were prepared by a cost-effective wet process. Structural and chemical characterizations were performed using X-ray diffraction, scanning electron microscopy, and X-ray photoelectron spectroscopy. The values of electrical conductivity and the Seebeck coefficient were measured near room temperature. A high value of the power factor (1.55 μW m-1 K-2 at 320 K) was achieved for thin films treated with anti-solvent.

    Top-down approach using supercritical carbon dioxide ball milling for producing sub-10 nm Bi2Te3 grains
    We compare Bi2Te3 powders prepared by conventional ball milling to powders milled in supercritical carbon dioxide (scCO(2)). We demonstrate that scCO(2) milling overcomes size-reduction limitations reported for conventional milling. XRD and TEM reveal nanograins with smaller average sizes (< 10 nm) and narrower grain size distributions in the scCO(2) milled case. scCO(2) milling also preserves the crystallinity and shows less oxidation than conventional milling. This is the first report of Bi2Te3 with a sub-10 nm grain size whilst conserving high quality crystallinity, made using a top-down approach. Our study offers a route for developing unprecedentedly fine bulk nanostructured Bi2Te3-based thermoelectric materials.

    Hybrid-Halide Perovskite Thin Film Growth for Thermoelectric Applications
    Thermoelectric effect can convert thermal energy into electricity without any moving parts or vibrations in light or dark. These can be promising advantages to develop sustainable energy source for internet of things devices. In this regards, thin films of hybrid-halide perovskites, methylamonium tin iodide, were fabricated by spin coating technique on a glass substrate at different annealing times. Thin films were structurally and chemically characterized by x-ray diffraction pattern and a scanning electron microscope. Thermoelectric parameters were measured near room temperature. During optimization, thin films annealed for 5 min at 100°C shows the high performance with electrical conductivity 3.56 S/cm, Seebeck coefficient 66.03 μV/K and power factor of 1.55 μW/m K2 at 50°C. Thermoelectric performance from these hybrid-halide perovskite will help for further development of direct thermal energy harvesting devices near room temperature.

    Interface engineering using Y2O3 scaffold to enhance the thermoelectric performance of CsSnI3 thin film
    Solution processed Cesium Tin halide perovskites (CsSnI3) are inorganic crystal to be explored for thermoelectric applications. Here, we report a novel strategy using an inorganic Y2O3 scaffold to improve the thermoelectric performance. The additional Y2O3 influence the CsSnI3 crystal growth and favor more conducting behavior with intrinsic defects (Sn4+) formation. Therefore, the resulting solution processed composite film Y2O3/CsSnI3 show much improved electrical conductivity of ~310 S/cm as compared to ~98 S/cm of pristine CsSnI3 film. Under the influence of Y2O3, the resulting phonon scattering path was enhanced significantly due to formed defects/vacancy and reduced CsSnI3 crystal size, which showed a reduction in thermal conductivity from 0.74 W/mK to 0.28 W/mK. This work paves a new paradigm to improve the thermoelectric performance of solution based thermoelectric generator.

    The influence of Y2O3 nanolayers on thermoelectric performance and structure of 2&#37; Al-doped ZnO (AZO) thin films has been studied. Multilayers based on five 50 nm thick AZO layers alternated with few nanometers thick Y2O3 layers were prepared by pulsed laser deposition on Al2O3 single crystals by alternate ablation of AZO target and Y2O3 target. The number of laser shots on Y2O3 target was maintained very low (5, 10 and 15 pulses in three separate experiments. The main phase (AZO) presents polycrystalline orientation and typical columnar growth not affected by the presence of Y2O3 nanolayers. The multilayer with 15 laser shots of Y2O3 showed best thermoelectric performance with electrical conductivity sigma = 48 S/cm and Seebeck coefficient S=-82 mu V/K, which estimate power factor (S-2.sigma) about 0.03 x 10(-3) W m(-1) K-2 at 600 K. The value of thermal conductivity (kappa) was found 10.03 W m(-1) K-1 at 300 K, which is one third of typical value previously reported for bulk AZO. The figure of merit, ZT = S-2 .sigma . T/kappa, is calculated 9.6 x 10(-4) at 600 K. These results demonstrated the feasibility of nanoengineered defects insertion for the depression of thermal conductivity.

    Thermal phonon transport in single-crystalline Si thin films with dog-leg shaped nanostructures was investigated. Thermal conductivities for the forward and backward directions were measured and compared at 5 and 295K by micro thermoreflectance. The Si thin film with dog-leg shaped nanostructures showed lower thermal conductivities than those of nanowires and two-dimensional phononic crystals with circular holes at the same surface-to-volume ratio. However, asymmetric thermal conductivity was not observed at small temperature gradient condition in spite of the highly asymmetric shape though the size of the pattern is within thermal phonon mean free path range. We conclude that strong temperature dependent thermal conductivity is required to observe the asymmetric thermal phonon conduction in monolithic materials with asymmetric nanostructures.

    After more than three decades of molecular and carbon-based electronics, the creation of air-and thermally stable n-type materials remains a challenge in the development of future p/n junction devices such as solar cells and thermoelectric modules. Here a series of ordinary salts are reported such as sodium chloride (NaCl), sodium hydroxide (NaOH), and potassium hydroxide (KOH) with crown ethers as new doping reagents for converting single-walled carbon nanotubes to stable n-type materials. Thermoelectric analyses reveal that these new n-type single-walled carbon nanotubes display remarkable air stability even at 100 degrees C for more than 1 month. Their thermoelectric properties with a dimensionless fi gure-of-merit (ZT) of 0.1 make these new n-type single-walled carbon nanotubes a most promising candidate for future n-type carbon-based thermoelectric materials.

    On-chip thermoelectric thin film modules containing 5 legs of n-type (Al0.02Zn0.98O) and 5 legs of p-type (Ca3Co4O9) were fabricated on Al2O3, SrTiO3 single crystal, and fused silica substrates by pulsed laser deposition technique. Performance of modules was evaluated using ad hoc customized system where the module was set vertically for temperature gradient. The maximum output power (P-max) was obtained on Al2O3 (0001) single crystal substrate with temperature difference (Delta T) = 230 degrees C (T-h = 300 degrees C): P-max = 29.9 pW. The value of maximum output power increases with increase of temperature difference (Delta T) These results are encouraging for the practical applications of thermoelectric oxide thin films.

    The influence of self-grown seed has been studied on thermoelectric performance of 2&#37; Al-doped ZnO(AZO) thin films. The thickness and orientation of c-axis domains in seed layer change on different substrates while other deposition conditions were kept unchanged for a comparable study. The changes occur because of the different nucleation process of thin film growth on substrate interface and the different lattice mismatch between AZO and substrate. Thin films are grown by pulsed laser deposition on single crystals (SrTiO3 (STO) and Al2O3) and cheap amorphous fused silica (FS) substrates at 400 degrees C. All thin films are c-axis oriented. The grains are highly connected and elongated in shape which leads to high thermoelectric properties. The thicker self-grown seed layer is found in thin film deposited on FS substrates which shows best performance: electrical conductivity sigma = 93 S/cm and Seebeck coefficient S = -203 mu V/K, which estimate power factor (S-2.sigma) about 0.37 x 10(-3) Wm(-1)K(-2) at 600 K. The value of thermal conductivity (kappa) was found lowest (4.89 Wm(-1)K(-1)) for thin film deposited on FS than the other thin films (6.9 Wm(-1)K(-1) on Al2O3 and 6.55 Wm(-1)K(-1) on STO) at 300 K. The figure of merit, ZT = S-2.sigma.T/kappa, is calculated 0.046 at 600 K, 5 times larger than the ZT of our previous reported bulk AZO, which is promising for practical applications of thermoelectric oxide thin films.

    The microstructure of materials affects thermal and electrical transport as well as the physical properties. The effects of the microstructure on both thermal and electrical transport in silicon membranes with periodic microporous structures produced from silicon-on-insulator wafers using microfabrication processes were studied. The in-plane thermal and electrical conductivities of the Si membranes were measured simultaneously by using a self-heating method. The measured thermal conductivity was compared with the result from the periodically laser-heating method. The thermal and electrical conductivities were much lower in the porous membranes than in the non-porous membrane. The measured thermal conductivity was much lower than expected based on values determined using classical models. A significant phonon size effect was observed even in microsized structures, and the mean free path for phonons was very long. It was concluded that phonon transport is quasi-ballistic and electron transport is diffuse in microporous Si structures. It was suggested that the microstructure had a different effect on thermal and electrical transport.

  • Enhanced thermoelectric properties of phase-separating bismuth selenium telluride thin films via a two-step method

    A two-step method that combines homogeneous electron beam (EB) irradiation and thermal annealing has been developed to enhance the thermoelectric properties of nanocrystalline bismuth selenium telluride thin films. The thin films, prepared using a flash evaporation method, were treated with EB irradiation in a N-2 atmosphere at room temperature and an acceleration voltage of 0.17 MeV. Thermal annealing was performed under Ar/H-2 (5&#37;) at 300 degrees C for 60 min. X-ray diffraction was used to determine that compositional phase separation between bismuth telluride and bismuth selenium telluride developed in the thin films exposed to higher EB doses and thermal annealing. We propose that the phase separation was induced by fluctuations in the distribution of selenium atoms after EB irradiation, followed by the migration of selenium atoms to more stable sites during thermal annealing. As a result, thin film crystallinity improved and mobility was significantly enhanced. This indicates that the phase separation resulting from the two-step method enhanced, rather than disturbed, the electron transport. Both the electrical conductivity and the Seebeck coefficient were improved following the two-step method. Consequently, the power factor of thin films that underwent the two-step method was enhanced to 20 times (from 0.96 to 21.0 mu W/(cmK(2)) that of the thin films treated with EB irradiation alone.

    We have estimated the thermal conductivity of nanocrystalline bismuth telluride thin films using the differential 3 omega method, taking into account the thermal contact resistance (TCR) between the substrate and thin-film layers. The thin films were prepared on alumina substrates by radio-frequency (RF) magnetron sputtering at temperature of 200A degrees C. Film thickness varied between 0.8 mu m and 3.1 mu m. The structural properties of the films were analyzed using x-ray diffraction analysis. Their electrical conductivity, Seebeck coefficient, and power factor were evaluated. For measurement of thermal properties by the differential 3 omega method, SiO2 thin films were deposited onto the samples, to act as insulating layers. Thin aluminum wire was then patterned onto the SiO2 layer. The observed variations in temperature amplitude as a function of film thickness indicated that the TCR contribution was very small and could therefore be neglected when estimating the thermal conductivity of the thin films. The thermal conductivity of the nanocrystalline bismuth telluride thin films with thickness of 0.8 mu m and 2.1 mu m were determined to be 0.55 W/(m K) and 0.48 W/(m K), respectively.

    To investigate the effect of strain on bismuth telluride films, we applied different compressive and tensile strains to thin films by changing the bending radius of a flexible substrate so the strain ranged from -0.3&#37; (compressive) to +0.3&#37; (tensile). The structural properties of the strained thin films, composed of nanosized grains, were analyzed by x-ray diffraction and scanning electron microscopy. For all samples the main peak was the (015) diffraction peak; crystal orientation along the (015) growth direction was slightly enhanced by application of compressive strain. The thermoelectric properties of strained bismuth telluride thin films were evaluated by measurement of electrical conductivity, Seebeck coefficient, and power factor. The magnitude and direction of the applied strain did not significantly affect the power factor, because when the strain changed from compressive to tensile the electrical conductivity increased and the absolute Seebeck coefficient decreased.

Thin films were grown by pulsed laser deposition on sapphire () substrates at various deposition temperatures ( to ). All films were c-axis oriented. The electrical conductivity of AZO-V thin films was higher than that of AZO-O thin films across the whole temperature range from 300 K to 600 K, due to the optimal carrier concentration () of AZO-V samples. Furthermore, the thermoelectric performance of AZO-V films increased with the deposition temperature; for instance, the highest power factor of and dimensionless figure of merit of 0.07 at 600 K were found for AZO-V thin film deposited at .

    To investigate the effect of strain on specific heat, sound velocity and lattice thermal conductivity of nanocrystalline bismuth antimony telluride thin films, we performed both experimental study and modeling. The nanocrystalline thin films had mostly preferred crystal orientation along c-axis, and strains in the both directions of c-axis and a-b-axis. It was found that the thermal conductivity of nanocrystalline thin films decreased greatly as compared with that of bulk alloys. To gain insight into the thermal transport in the strained nanocrystalline thin films, we estimated the lattice thermal conductivity based on the phonon transport model of full distribution of mean free paths accounting for the effects of grain size and strain which was influenced to both the sound velocity and the specific heat. As a result, the lattice thermal conductivity was increased when the strain was shifted from compressive to tensile direction. We also confirmed that the strain was influenced by the lattice thermal conductivity but the reduction of the lattice thermal conductivity of thin films can be mainly attributed to the nano-size effect rather than the strain effect. Finally, it was found that the measured lattice thermal conductivities were in good agreement with modeling.

    The effects of homogeneous irradiation of electron beam (EB) on the crystal growth and thermoelectric properties of nanocrystalline bismuth selenium telluride thin films were investigated. The thin films were prepared using a flash evaporation method, after which EB irradiation was performed under N-2 at room temperature at an accelerated voltage of 0.17 MeV. SEM revealed that the untreated thin film was composed of a large quantity of rice-like nanostructures. With increasing the EB irradiation dose, a number of nanodots with diameters of less than 10 nm became visible on the surface of the rice-like nanostructures. The crystallinity and the crystal orientation were enhanced with increasing EB irradiation dose while the average crystal grain size remained almost the same size as that of the untreated thin film. In terms of thermoelectric properties, the mobility of the thin films was enhanced as the EB irradiation dose was increased while the carrier concentration was not greatly changed. As a result, both the electrical conductivity and the Seebeck coefficient were improved with increasing EB irradiation dose. Consequently, even though there is still room for further improvement, the power factor was enhanced around sevenfold (from 0.14 to 0.96 mu W/cm/K-2) by the EB irradiation treatment.

    We investigated the effects of strain and grain size on the thermal transport of highly-oriented nanocrystalline bismuth antimony telluride thin films using both experimental studies and modeling. The fabricated thin films had preferred crystal orientation along the c-axis, average grain sizes of 30 < d < 100 nm, and strain of -0.8&#37; < epsilon < -1.4&#37; in the c-axis direction, whereas the strain in the a-b-axis direction was constant at 1.7&#37;. The thermal conductivities were measured to be 0.32 < k < 0.52 W/m/K using a 3 omega method at room temperature. To gain insight into the thermal transport in the strained nanocrystalline thin films, we estimated the lattice thermal conductivities from the measured thermal conductivities. We then calculated the lattice thermal conductivity using a simplified phonon transport model that accounts for the strain effect based on the Christoffel equation and uses Lennard-Jones potentials, and the grain size effect based on the full distribution of mean free paths. The theoretical calculations were in good agreement with our experimental results, and we conclude that the decrease of the lattice thermal conductivity of nanocrystalline thin films can be mainly attributed to the nano-size effect rather than the strain effect.

    The effects of homogenous electron beam (EB) irradiation on the crystal growth and thermoelectric properties of n-type Bi-Se-Te and p-type Bi-Sb-Te thin films were investigated. Both types of thin films were prepared by flash evaporation, after which homogeneous EB irradiation was performed at an acceleration voltage of 0.17MeV. For the n-type thin films, nanodots with a diameter of less than 10nm were observed on the surface of rice-like nanostructures, and crystallization and crystal orientation were improved by EB irradiation. The resulting enhancement of mobility led to increased electrical conductivity and thermoelectric power factor for the n-type thin films. In contrast, the crystallization and crystal orientation of the p-type thin films were not influenced by EB irradiation. The carrier concentration increased and mobility decreased with increased EB irradiation dose, possibly because of the generation of defects. As a result, the thermoelectric power factor of p-type thin films was not improved by EB irradiation. The different crystallization behavior of the n-type and p-type thin films is attributed to atomic rearrangement during EB irradiation. Selenium in the n-type thin films is more likely to undergo atomic rearrangement than the other atoms present, so only the crystallinity of the n-type Bi-Se-Te thin films was enhanced.

The thermoelectric properties of AZO thin films were studied in a low temperature range (300-600 K). Thin film deposited at 300 A degrees C is fully c-axis-oriented and presents electrical conductivity 310 S/cm with Seebeck coefficient -65 mu V/K and power factor 0.13 x 10(-3) Wm(-1) K-2 at 300 K. The performance of thin films increases with temperature.

The cross-plane thermal conductivities of the porous p- and n-type thin films were 0.4 W m(-1) K-1 and 0.42 W m(-1) K-1, respectively, and the dimensionless figures of merit, ZT, of the p- and n-type BiTe films were estimated as 1.0 and 1.0, respectively, at room temperature. A prototype thermoelectric module consisting of 20 pairs of p- and n-type strips over an area of 3 cm x 5 cm was fabricated on the porous PI substrate. This module produced an output power of 0.1 mW and an output voltage of 0.6 V for a temperature difference of 130A degrees C. The output power of the submicrostructured module was 1.5 times greater than that of a module based on smooth BiTe-based thin films. Thus, the thermoelectric performance of the thin films was improved owing to their submicroscale structure.

    2&#37; Al-doped ZnO (AZO) thin films fabricated at 300 C by pulsed laser deposition (PLD) on amorphous fused silica demonstrated the high quality crystallinity and grain connection, which correlates to the high thermoelectric performance: electrical conductivity sigma = 923S/cm and Seebeck coefficient S = -111 mu V/K at 600 K. Its power factor (S-2 center dot sigma) is 1.2 x 10(-3)Wm(-1)K(-2), twofold better than films deposited on crystalline SrTiO3 under the same experimental conditions. Using our measured thermal conductivity (kappa) at 300K (4.89Wm(-1)K(-1)), the figure of merit, ZT = (S-2 center dot sigma center dot T/kappa), is calculated as 0.045 at 600 K, 5 times larger than ZT of our previously reported bulk ZnO.

    We have investigated the origin of crystal orientation for nanocrystalline bismuth telluride-based thin films. Thin films of p-type bismuth telluride antimony (Bi-Te-Sb) and n-type bismuth telluride selenide (Bi-Te-Se) were fabricated by a flash evaporation method, with exactly the same deposition conditions except for the elemental composition of the starting powders. For p-type Bi-Te-Sb thin films the main x-ray diffraction (XRD) peaks were from the c-axis (I {00l} pound/I {hkl} pound = 0.88) whereas n-type Bi-Te-Se thin films were randomly oriented (I {00l} pound/I {hkl} pound = 0.40). Crystal orientation, crystallinity, and crystallite size were improved for both types of thin film by sintering. For p-type Bi-Te-Sb thin films, especially, high-quality structures were obtained compared with those of n-type Bi-Te-Se thin films. We also estimated the thermoelectric properties of the as-grown and sintered thin films. The power factor was enhanced by sintering; maximum values were 34.9 mu W/cm K-2 for p-type Bi-Te-Sb thin films at a sintering temperature of 300A degrees C and 23.9 mu W/cm K-2 for n-type Bi-Te-Se thin films at a sintering temperature of 350A degrees C. The exact mechanisms of film growth are not yet clear but we deduce the crystal orientation originates from the size of nano-clusters generated on the tungsten boat during flash evaporation.

    We prepared both n- and p-type bismuth telluride thin films by using a coaxial-type vacuum arc evaporation method. The atomic compositions of the as-grown thin films and several annealed thin films were comparable to that of bulk bismuth telluride. Their thermoelectric properties were measured and found to be comparable to those of bulk materials. The Seebeck coefficient and electrical conductivity of the as-grown thin films were improved by the annealing process. The measured figures of merit (ZT) of the films were 0.86 for the n-type and 0.41 for the p-type at 300 K for annealing temperatures of 573 K and 523 K, respectively.

In the mixture, the organic components (PEDOT:PSS, PAA and an additive) act as a binder to connect bismuth telluride particles mechanically and electrically. Among the organic additives used, glycerol significantly enhanced the electrical conductivity and bismuth telluride particle dispersibility in the mixture. Bi0.4Te3.0Sb1.6 films fabricated by spin-coating the mixture showed a thermoelectric figure of merit (ZT) of 0.2 at 300 K when the Bi0.4Te3Sb1.6 particle diameter was 2.8 μm and its concentration in the elastic films was 95 wt.&#37;. © 2013 TMS.

    We have prepared 2&#37; Al doped ZnO (AZO) thin films on SrTiO3 (STO) and Al2O3 substrates by Pulsed Laser Deposition technique at various deposition temperatures (Tdep = 300°C-600°C). Transport and thermoelectric properties of AZO thin films were studied in low temperature range (300 K-600 K). AZO/STO films present superior performance respect to AZO/Al2O3 films deposited at the same temperature, except for films deposited at 400°C. Best film is the fully c-axis oriented AZO/STO deposited at 300°C, which epitaxial strain and dislocation density are the lowest: electrical conductivity 310 S/cm, Seebeck coefficient -65 μV/K, and power factor 0.13 × 10-3 W m-1 K-2 at 300 K. Its performance increases with temperature. For instance, power factor is enhanced up to 0.55 × 10 -3 W m-1 K-2 at 600 K, surpassing the best AZO film previously reported in literature. © 2013 AIP Publishing LLC.

    We have reported the growth of single-crystalline bismuth antimony telluride nanoplates on the surface of nanoparticle thin films using a simple sintering process. We prepared two types of bismuth antimony telluride thin films, one comprising nanoparticles and the other submicron particles. The nanoplates were found to grow only on thin films comprising nanoparticles. The structure, composition, and morphology of nanoplates were investigated by using X-ray diffractometry, scanning electron microscopy, transmission electron microscopy, and energy-dispersive X-ray analysis. The obtained nanoplates were of length 0.5-1 mu m and thickness less than 100 nm. The atomic composition of the nanoplates was almost the same as that of the nanoparticles in the thin films. The nanoplates were found to be single crystalline, while the nanoparticles in the thin films were polycrystalline in nature. The growth of nanoplates on the surface of the thin films was due to the partial melting and evaporation of nanoparticles during the sintering process. As a result, the evaporated materials formed nuclei on the surface of the films, which then crystallized to form nanoplates. (C) 2013 Elsevier B.V. All rights reserved.

    Here, we investigate the combined effect of the nanoscale crystal grains and porosity on the lattice thermal conductivity of bismuth-telluride-based bulk alloys using both experimental studies and modeling. The fabricated bulk alloys exhibit average grain sizes of 30 < d < 60nm and porosities of 12&#37; < Phi < 18&#37;. The total thermal conductivities were measured using a laser flash method at room temperature, and they were in the range 0.24 to 0.74W/m/K. To gain insight into the phonon transport in the nanocrystalline and nanoporous bulk alloys, we estimate the lattice thermal conductivities and compare them with those obtained from a simplified phonon transport model that accounts for the grain size effect in combination with the Maxwell-Garnett model for the porosity effect. The results of this combined model are consistent with the experimental results, and it shows that the grain size effect in the nanoscale regime accounts for a significant portion of the reduction in lattice thermal conductivity.

    We fabricated in-plane thermoelectric modules (4 mm x 4 mm) on a 4-m-thick substrate using a vacuum deposition process through a shadow mask. In this study, a thermoelectric - pair was established using multilayered films of and thermoelectric thin films and an insulator film with a hole at the center. The output power was 58 nW at 443 K using the multilayered microgenerator. We discuss the effects of device thickness on the efficiency of the microgenerator to increase the output electric power. We evaluated the output power of the in-plane thermoelectric generator with a substrate using a one-dimensional heat conduction model, and it was found to depend on the thickness of the thermoelectric film. If the thermoelectric film is very thin, the power factor is more important than the nondimensional figure of merit, . Metal thin films with high power factor are more efficient than semiconductors with low power factors even though their thermal conductivities are high. When the thermoelectric thin film is thick, should be higher for larger output power of the device.

    In this study, we introduce our numerical and experimental works for the thermal conductivity reduction by using a porous material. Recently thermal conductivity reduction has been one of the key technologies to enhance the figure of merit (ZT) of a thermoelectric material. We carry out numerical calculations of heat conduction in porous materials, such as phonon Boltzmann transport (BTE) and molecular dynamics (MD) simulations, in order to investigate the mechanism of the thermal conductivity reduction of a porous material. In the BTE, we applied the periodic boundary conditions with constant heat flux to calculate the effective thermal conductivity of porous materials.In the MD simulation, we calculated the phonon properties of Si by using the Stillinger-Weber potential at constant temperature with periodic boundary conditions in the x, y, and z directions. Phonon dispersion curves of single crystal of Si calculated from MD results by time-space 2D FFT are agreed well with reference data. Moreover, the effects of nanoporous structures on both the phonon group velocity and the phonon density of states (DOS) are discussed. At last, we made a porous p-type Bi2Te3 by nanoparticles prepared by a beads milling method. The thermal conductivity is one-fifth of that of a bulk material as well as keeping the same Seebeck coefficient as the bulk value. However, electrical conductivity was much reduced, and the ZT was only 0.048. [DOI: 10.1115/1.4005709]

    Process optimization of preparing honeycomb-patterned polystyrene films by breath figure method
    Honeycomb-patterned polystyrene film is prepared by breath figure method. Pore size with a few hundred nano-meter to several micro-meter diameters is generated by controlling various parameters, such as the polymer concentration, humidity, casting area and solvent. The pore size becomes larger with increasing humidity and temperature difference between air and substrate. Porous film can be formed by drying under high humidity. The density of solvents affect the pore shape and pore depth. Video observation indicates that in the formation process of the porous pattern water droplet condenses gradually on the surface, along with the migration of the droplet formation boundary line from the edge to the center, when the boundary line reaches the center, hexagonally packed porous template is completed.

    The cross-plane thermal conductivity of highly oriented nanocrystalline bismuth antimony telluride thin films is investigated. The thin film was deposited by a flash evaporation method. The resulting film was oriented with the c-axis to the substrate, and was composed of fine grains with an average grain size of 150 nm. The cross-plane thermal conductivity of the film was measured by a 3 omega method at room temperature, and was determined to be 0.6 W m(-1) K(-1). Compared to the single crystal bulk alloy of nearly the same composition and carrier concentration, the thin film exhibited a 20&#37; reduction in the thermal conductivity. (c) 2009 Elsevier B.V.

    Using shadow masks prepared by standard microfabrication processes, we fabricated in-plane thermoelectric microdevices (4 mm x 4 mm) made of bismuth telluride thin films, and evaluated their performance. We used Bi0.4Te3.0Sb1.6 as the p-type semiconductor and Bi2.0Te2.7Se0.3 as the n-type semiconductor. We deposited p- and n-type thermoelectric thin films on a free-standing thin film of Si3N4 (4 mm x 4 mm x 4 mu m) on a Si wafer, and measured the output voltages of the microdevices while heating at the bottom of the Si substrate. The maximum output voltage of the thermoelectric device was 48 mV at 373 K.

    The spectral reflectance of microperiodic structures of silica microspheres was investigated. The electromagnetic dispersion relation in a close-packed structure of silica spheres is computed. The three-dimensional close-packed structures, self-assembled with silica microspheres (2 mu m and 3 mu m), were rapidly fabricated over a large area. Specular reflectance was measured by using Fourier transform-infrared spectroscopy (FT-IR). The experimental results were evaluated by a modification of Bragg's law, taking into account Snell's law of refraction, and calculations of multiple reflections and the scalar wave approximation method. In addition, to expand the reflection wavelength range, a double-layered sample was fabricated, and its spectral reflectance was determined.

    Visualization and Numerical Analysis of Unsteady Flow in Pump Sump
    Numerical and experimental studies were done on unsteady flow in a pump sump to study the generation of air core vortex and submerged vortex, which cause vibration and acoustic noise. The geometry of the free surface in the test pump sump was visualized by Moire method, and velocities near pump suction were measured by PIV. Unsteady flow in the pump sump was calculated using VOF method in a commercial CFD software, and calculated velocities as well as free surface geometry were compared with measured ones. The present study showed that CFD can capture unsteady flow in a pump sump with a reasonable accuracy, and that the air core vortex as well as submerged vortex can be predicted by CFD.

    The effect of grain size on the thermoelectric properties of n-type nanocrystalline bismuth-telluride based thin films is investigated. We prepare the nanocrystalline thin films with average grain sizes of 10, 27, and 60 nm by a flash-evaporation method followed by a hydrogen annealing process. The thermoelectric properties, in terms of the thermal conductivity by a differential 3 omega method, the electrical conductivity, and the Seebeck coefficient are measured at room temperature and used to evaluate the figure of merit. The minimum thermal conductivity is 0.61 W m(-1) K(-1) at the average grain size of 10 nm. We also estimate the lattice thermal conductivity of the nanocrystalline thin films and compare it with a simplified theory of phonon scattering on grain boundaries. For nanosized grains, the lattice thermal conductivity of nanocrystalline thin films decreases rapidly for smaller grains, corresponding to the theoretical calculation. The figure of merit is also decreased as the grain size decreases, which is attributed to the increased number of defects at the grain boundaries. (C) 2008 American Institute of Physics.

    An inverse transient method with genetic algorithm (GA) was applied to leak detection in pipeline. Transient flow caused by valve operation was calculated using the characteristics method. The location and discharge of leak were determined so that the difference of the calculated pressure may be minimized from the reference pressure calculated under a given leak condition. Calculations were done for the leak at one and two locations in pipeline. Furthermore, the effect of noise in pressure data was discussed, and the leak locations and leak discharges can he predicted precisely even in the case of noisy data.

    In this article, we perform a preliminary study to assemble micro-size thermoelectric devices with low-cost fabrication by a preparation of nanoparticles and their thin films. Bi0.4TC3.0Sb1.6 nanoparticles with an average size of approximately 50nm are fabricated by a beads-milling method. The nanoparticle solution is prepared by mixing with toluene and a surfactant, and thin films with 1 mu m thick are deposited on Al2O3 substrates by a printing method. The thin films are sintered at temperatures ranging from 300 to 500 degrees C for 60 min in hydrogen ambient. We investigate the thin film structures and the thermoelectric properties at room temperature. As the sintering temperature increases, hexagonal-shaped crystals are grown on the film surface while the atomic composition is almost constant throughout all the sintering temperatures. The XRD patterns indicate that all the nanoparticle thin films are found to mostly exhibit the same XRD intensities and have multiple peaks correspond to each other. The in-plane electrical conductivity of the thin films increases but. the Seebeck coefficient decreases as the sintering temperature increases. As a result, the best performance of the thermoelectric power factor of 1.3 mu W/(cm K-2) is achieved at a sintering temperature of 350 degrees C. (C) 2007 Elsevier B.V. All rights reserved.

    Structural and thermoelectric properties of p-type fine-grained Bi(0.4)Te(3.0)Sb(1.6) thin films are investigated. The films are deposited by a flash evaporation method and exhibit a preferred orientation in the c-axis direction. By optimizing deposition conditions, we achieve thin films with clean surfaces. Then in order to enhance the crystallinity with preferred orientation, as well as the thermoelectric properties of the thin films, they are annealed in hydrogen ambient at atmospheric pressure and at temperatures ranging from 200 to 350 'C. The cross-section microstructure and crystallinity of the thin films are investigated by scanning electron microscopy and X-ray diffraction, respectively. The electrical conductivity, Seebeck coefficient, and thermoelectric power factor are measured at room temperature. We confirm that the grain growth and the crystallization along the c-axis are enhanced as the annealing temperature increases. The highest performance of p-type Bi(0.4)Te(3.0)Sb(1.6) thin films observed in this study have an annealing temperature of 300 degrees C, resulting in a thennoelectric power factor of 34.9 mu W cm(-1) K(-2) at the average grain size of 88 nm. We consider that the synthesis conditions reduce the number of potential scattering sites at grain boundaries and defects, thus improving the thermoelectric power factor.

    Bi0.4Te3.0Sb1.6 thin films on glass substrates are fabricated by a flash evaporation method. In order to enhance the transport properties of the thin films, annealing in argon ambient at atmospheric pressure is carried out for 1 h in the temperature range from 200 to 400 degrees C. The structure of the thin films, in terms of homogeneous composition and crystallinity, is investigated by energy dispersive X-ray spectroscopy and X-ray diffraction, respectively. The microstructure of the thin films is examined using scanning electron microscopy. We confirm that as-deposited Bi0.4Te3.0Sb1.6 thin films have a mostly homogeneous structure except for a few extra stuck particles. At higher annealing temperatures, the crystallinity of the thin films is improved and the size of crystal grains increases to the same size as the film thickness. However, excessive high annealing temperatures cause porous thin films due to the evaporation of tellurium. The transport properties of the thin films, in terms of the electrical resistivity, the Seebeck coefficient and the thermoelectric power factor are determined at room temperature. By optimizing the annealing conditions, it is possible to obtain a high-performance thin film with a thermoelectric power factor of 12.2 mu W cm(-1) K-2. We consider that the performance of the thin films is enhanced for optimized annealing because of reductions in the importance of grain boundary scattering. (C) 2006 Elsevier B.V.

    Bismuth-telluride-based alloy thin film thermoelectric generators are fabricated by a flash evaporation method. We prepare Bi0.4Te3.0Sb1.6 (P-type) and Bi2.0Te2.7Se0.3 (n-type) powders for the fabrication of the flash evaporated thin films. The overall size of the thin film thermoelectric generators, which consist of seven pairs of legs connected by aluminum electrodes, is 20 mm by 15 mm. Each leg is 15 turn long, 1 turn wide and 1 mu m thick. We measure the output voltage and estimate the maximum output power near room temperature as a function of the temperature difference between hot and cold junctions of the thin film thermoelectric generators. In order to improve the performance of the generators, a hydrogen annealing process is carried out at several temperatures from 25 degrees C to 250 degrees C. The highest output voltage of 83.3 mV and estimated Output power of 0.21 mu W are obtained from a hydrogen annealing temperature of T-a = 250 degrees C and a temperature difference of Delta T = 30 K. The hydrogen annealing temperature of T-a = 250 degrees C also results in the best electrical performance for both p-type thin film (Seebeck coefficient= 254.4 mu V/K, resistivity = 4.1 m Omega cm, power factor = 15.9 mu W/cm K-2) and n-type thin film (- 179.3 mu V/K, 1.5 m Omega cm, 21.5 mu W/cm K-2).

    The thermal conductivity of n-type nanocrystalline bismuth-telluride-based thin films (Bi2.0Te2.7Se0.3) is investigated by a differential 3 omega method at room temperature. The nanocrystalline thin films are grown on a glass substrate by a flash evaporation method, followed by hydrogen annealing at 250 degrees C. The structure of the thin films is studied by means of atomic force microscopy, x-ray diffraction, and energy-dispersive x-ray spectroscopy. The thin films exhibit an average grain size of 60 nm and a cross-plane thermal conductivity of 0.8 W/m K. The in-plane electrical conductivity and in-plane Seebeck coefficient are also investigated. Assuming that the in-plane thermal conductivity of the thin films is identical to that of the cross-plane direction, the in-plane figure of merit of the thin films is estimated to be ZT=0.7. As compared with a sintered bulk sample with average grain size of 30 mu m and nearly the same composition as the thin films, the nanocrystalline thin films show approximately a 50&#37; reduction in the thermal conductivity, but the electrical conductivity also falls 40&#37;. The reduced thermal and electrical conductivities are attributed to increased carrier trapping and scattering in the nanocrystalline film. (c) 2007 American Institute of Physics.

    The structure and thermoelectric properties of boron doped nanocrystalline Si0.8Ge0.2 thin films are investigated for potential application in microthermoelectric devices. Nanocrystalline Si0.8Ge0.2 thin films are grown by low-pressure chemical vapor deposition on a sandwich of Si3N4/SiO2/Si3N4 films deposited on a Si (100) substrate. The Si0.8Ge0.2 film is doped with boron by ion implantation. The structure of the thin film is studied by means of atomic force microscopy, x-ray diffraction, and transmission electron microscopy. It is found that the film has column-shaped crystal grains similar to 100 nm in diameter oriented along the thickness of the film. The electrical conductivity and Seebeck coefficient are measured in the temperature range between 80-300 and 130-300 K, respectively. The thermal conductivity is measured at room temperature by a 3 omega method. As compared with bulk silicon-germanium and microcrystalline film alloys of nearly the same Si/Ge ratio and doping concentrations, the Si0.8Ge0.2 nanocrystalline film exhibits a twofold reduction in the thermal conductivitity, an enhancement in the Seebeck coefficient, and a reduction in the electrical conductivity. Enhanced heat carrier scattering due to the nanocrystalline structure of the films and a combined effect of boron segregation and carrier trapping at grain boundaries are believed to be responsible for the measured reductions in the thermal and electrical conductivities, respectively.

    The phonon Boltzmann equation is solved numerically in order to study the phonon thermal conductivity of micro/nanostructured thin films with open holes in a host material. We focused on the size effect of embedded pores and film thickness on the decrease in thermal conductivity of the film. Simulations have revealed that the temperature profiles in the micro/nanostructured materials are very different from those in their bulk counterparts, due to the ballistic nature of the microscale phonon transport. These simulations clearly demonstrate that the conventional Fourier beat conduction equation cannot be applied to study heat conduction in solids at microscale. The effective thermal conductivity of thin films with micro/nanoholes is calculated from the applied temperature difference and the heat flux. In the present paper, the effective thermal conductivity is shown as a function of the size of the micro/nanoholes and the film thickness. For example, when the size of the hole becomes. approximately 1/20th the phonon mean free path in a film, the thickness is 1/10th the mean free path of phonons and the effective thermal conductivity decreases to as low as 6&#37; of the bulk value. The distribution of holes also affects the reduction in the effective thermal conductivity. Thin films embedded with staggered-hole arrays have slightly lower effective thermal conductivities than films with aligned-hole arrays. The cross-sectional area in the thermal transport direction is a significant parameter with respect to the reduction of thermal conductivity. The results of the present study may prove useful in the development of artificial micro/nanostructured materials, including thermoelectrics and low-k dielectrics.

    Molecular dynamics simulations on the thermal conductivity of Si-Ge superlattices
    We conducted molecular dynamics (MD) simulations on heat transfer in Si-Ge superlattices to investigate the effects of nano-structures on thermal conductivities. Both the perpendicular thermal conductivity to the interfaces (cross-plane) and the parallel one to the interfaces (in-plane) were calculated. The layered system had a lower conductivity than the uniform system. When the number of layers was increased while keeping the total sample thickness constant, the cross-plane thermal conductivity decreased. We calculated the kinetic energy profile to investigate the mechanism of this decrease. The motions of atoms at the boundaries between Si and Ge were suppressed, and it became thermal resistance.

    Temperature measurements with micro-TFTCs
    We fabricate metal thin film thermocouples (TFTCs). Au-Pt, Cu-Ni, and W-Ni are deposited on a glass plate using standard thin film processes. The dimension of thermocouple junction is 30μm×300μm. The thermoelectric powers of TFTCs are different from those of bulk because diffusion of electrons is restricted by the very thin film. However TFTCs are still useful for temperature measurements because the thermoelectric voltage is proportional to measured temperature at thermocouple junction. The response time of Au-Pt TFTCs is about 30ns when the surface of the glass is heated by a YAG pulsed laser. The result compares favorably with measurements by a thermoreflectance method. We also describe W-Ni nano-TFTCs with micro-heater fabricated by Focused Ion Beam for the measurement of absolute temperature distribution in 10 micron area. In order to reduce the size of the TFTCs we employ a 3-dimensional structure.

    Experimental study on unstable characteristics of mixed-flow pump at low flow-rates
    Static and dynamic characteristics of a mixed flow pump were measured at low flow rate, where the steady characteristic curves show a positive slope. Unsteady flow was measured at upstream and downstream of impeller, as well as on the casing wall of diffuser passage by using a fast response five-hole pitot tube and semi-conductor type pressure transducers. Dynamic response of the pump to the sinusoidal change in flow rate was measured under constant rotational speed. As a result of the unsteady flow measurements, the positive slope of steady characteristic was found to be caused by the impeller tip separation, inlet backflow, and pre-rotation. Moreover, the dynamic characteristics of the pump were found to become unstable with the increased frequency of flow rate.

    Molecular simulations using a genetic algorithm are conducted to investigate stable structures of clusters and deposited atoms on substrates. First, the stable structures of N-atom clusters are calculated. where an icosahedron is found to be the most stable form of a 13-atom cluster. Secondly, stable structures of deposited atoms on a solid surface are investigated. The simulation shows that deposited atoms have either an island or a layer structure, depending on the combination of intermolecular potentials between the deposited and substrate atoms. The present simulation is based on statics, which demands little computing power. (C) 2001 Elsevier Science B.V. All rights reserved.
