Profile
● Research We make a study of an ecologically friendly new material, which is rich-abundant and is made from non-toxic elements, for an electric device. For example, they are diamond which is a high-pressure and high-temperature phase, diamond-like carbon which is a non-equilibrium phase, beta iron disilicide which is a candidate semiconductor for an opt-electric device and the others. We fabricate them by the film preparation method using a laser and a plasma technology. In addition, we develop the film preparation system in cooperation with some small and medium enterprises. The detail subjects of the study are as follows. 【Low temperature growth of diamond films by pulsed laser deposition】 【Fabrication of hydrogen-free diamond-like carbon films by physical vapor depositions and their application for coating】 【Research concerning ecologically friendly semiconductors and their application for electric devices】 【Research in a semiconductor / ferromagnetic metal superlattice】 【Research in a new cathode material for a lithium ion battery】 【Development of the innovative film preparation system】 ● Education I belong to Department of Engineering Sciences for Electronics and Materials. My additional affiliation for graduate school education is Department of Applied Science for Electronics and Materials. Besides, I contribute to the undergraduate school education and have the following classes: “Lecture on mechanics and practice”, “Elemental experiment on physics” and “Soft energy for sustainability”. ● Social activities I contribute to the study group of The Japan Society of Applied Physics as a manager and contribute to Kyushu Chapter of The Japan Society of Applied Physics as an administrator. In Kyushu University, I hold a additional post as a technical advisor of Kyushu TLO Company, Limited. In the year 2003, I had lectures in an open class and a seminar of the graduate school. I have a lecture of the training institute organized by The Japan Cooperation agency (JICA) and Kyushu University.

    Ultrananocrystalline diamond/hydrogenated amorphous carbon composite (UNCD/a-C:H) film is a new candidate material applicable to optoelectronic devices owing to its unique electrical and optical properties. This paper describes a recent progress in the research on the application of semiconducting UNCD/a-C:H films to photodetectors. p-Type conduction accompanied by an enhancement in the carrier concentration was realized by boron doping. Spectral response measurement showed obvious photocurrent in the wavelength of shorter than 280 nm and above 500 nm, which probably originate from UNCD grains and mid-gap states owing to grain boundaries, respectively. Photodiodes comprising p-type UNCD/a-C:H films and n-type Si substrates exhibited a clear response for deep-ultraviolet light, and the external quantum efficiency and responsivity were more than 70% and 130 mA/W, respectively. It was experimentally proved that UNCD/a-C:H is a potential material for the application to photodetectors.

  • Production of p-Type Si/n-Type β-FeSi2 Heterojunctions Using Facing-Targets Direct-Current Sputtering and Evaluation of Their Resistance and Interface State Density Reviewed International journal

    215 ( 20 )   2018.10

     More details

    Language:English   Publishing type:Research paper (scientific journal)  

    Without a post-annealing procedure, the β-FeSi2 thin films are epitaxially grown on Si(111) wafer substrates via facing-targets direct-current sputtering. During epitaxial growth, the temperature for heating of substrates is maintained at 600 °C. The resultant p-type Si/n-type β-FeSi2 heterojunctions are produced. At room temperature, a large leakage current under an applied reverse bias voltage together with a small photo-detective performance is observed from the measured dark and irradiated current density–voltage curves of the created heterojunctions. Both of the conductance–voltage (G/ω–V) and capacitance–voltage (C–V) measurements at different frequencies (f) in the range of 5 kHz–1 MHz are performed in the dark at room temperature. The interface state density (Nss) and series resistance (Rs) in the created p-type Si/n-type β-FeSi2 heterojunctions are computed and analyzed from the measured C–V–f and G/ω–V–f curves. Nss is found to be 3.48 × 1012 eV−1 cm−2 at 5 kHz and decreased to 4.68 × 1011 eV−1 cm−2 at 1 MHz. Moreover, the values of Rs at zero bias are 2.21 kΩ at 5 kHz and 13.66 Ω at 1 MHz. These results review the presence of Nss and Rs in the created heterojunctions, and they can be the cause to degrade the heterojunction performance.

    Hydrogen passivation was applied to the initial epitaxial growth of n-type β-FeSi2 thin films on p-type Si(111) substrates by facing-targets direct-current sputtering (FTDCS) in order to reduced the formation of interface states and terminate dangling bonds in the β-FeSi2 films, and the passivation effects were studied on basis of the electrical evaluation results of the formed n-type β-FeSi2/p-type Si heterojunction photodiodes. The initial growth was made at different gas inflow H2/Ar ratios ranging from 0 to 0.2. The photodetection performance of the photodiode fabricated at the ratio of 0.2 was markedly improved as compared to those of the other samples. The quantum efficiency and detectivity were 2.08 % and 1.75 × 1010 cm√Hz/W, respectively. The sample exhibited the minimum junction capacitance density of 9.2 nF/cm2. The enhanced photodetective performance should be mainly because dangling bonds that act as trap centers for photocarriers are effectively inactivated by the passivation.

    n-Type β-FeSi2/p-type Si heterojunction, wherein the β-FeSi2 films were epitaxially grown on Si(111) substrates at a substrate temperature of 600 °C by facing-targets direct-current sputtering (FTDCS) without post-annealing, were structurally and electrically investigated. Three types of epitaxial variant of β-FeSi2 were confirmed by x-ray diffraction analysis. From the atomic force microscopic observations, it was found that the β-FeSi2 layer consists of a large number of rectangular crystallites with short sides of 50-100 nm. These are attributable to the variant epitaxial growth of β-FeSi2 on Si(111). The current-voltage characteristics of the heterojunction exhibited rectifying properties accompanied by large leakage and ideality factor greater than 2. This indicated that a tunneling effect contributes to the carrier conduction in the β-FeSi2 films. Therefore, the grain boundaries in the β-FeSi2 film act as trap and tunneling leakage centers, which degrades the photodetection performance of the β-FeSi2/Si photodiodes.

    Language:English   Publishing type:Research paper (scientific journal)  

    We investigated the effect of H2S annealing on Ag–In–S thin films prepared by vacuum evaporation. In thin films annealed above 350 °C, diffraction peaks except chalcopyrite AgInS2 phase were not observed for a starting material ratio of 1.0 but observed for that of 1.2. Thin films annealed at 400 °C with a starting material ratio of 1.5 contained several phases. We found that the Ag/In ratios of the films could be controlled by changing the starting material ratio. Grains of films with composition ratios of 1.0 and 1.2 were nonuniform, whereas those with a composition ratio of 1.5 were uniform.
