Profile
In our laboratory, we design nanoscale devices from a microscopic point of view using computational methods based on quantum mechanics, and develop multi-scale algorithms that enable to describe macroscopic dynamics from microscopic information. Specific examples of the research include the design of molecular devices by quantum transport calculations, and the design of electrochemical devices by first-principles and Monte Carlo calculations. In addition, we are developing quantum algorithms to utilize quantum computers, which have been developing rapidly in recent years, for research and development of molecular and solid state materials. We are also theoretically designing a new quantum computer by discovering new quantum phenomena.

Research Interests・Research Keywords

  • Research theme:<Atomistic flux simulation from first principles and Monte Carlo method> With the development of computers and first principles methods, we can investigate the stability, reactivity, and materials properties of bulk and interface systems from the atomistic point of view, although we still have the limitations on the system sizes and target materials. If the atomistic simulations can be applied to much larger systems in longer time-scale dynamics, the simulations will be very powerful tool for the precise designing of devices. However, first principles methods are in general limited to pico second dynamics for few hundreds of atoms, and in fact, there is a problem in which any answer cannot be obtained in such a limited simulation. To break through this upper limit extensively, we have developed a multi-scale dynamics approach, a parallelized kinetic Monte Carlo, on the basis of first principles electronic structure calculations. We are now working on the device designing from the atomistic point of view by using the multi-scale dynamics approach.

    Keyword:first principles method, Monte Carlo, Device designing

    Research period: 2019.9

  • Research theme:<Molecular device and quantum transport> Since chemical bonding between the organic molecule and the metal electrode is necessary for molecule-metal interfaces, a relatively strong bonding has an advantage for the robust interfaces. However, fluctuations in the bonding (i.e., adsorption) structures and its accompanied changes of the interface states and dipole result in complicated electronic states of organic molecules-metal interfaces. Although this is true, when an organic molecule is used as an electronic device, we can expect a tunneling current through the molecule. We clarified the correlation between the current path on the molecule and the electronic state of the molecule, which is important for the designing of the organic molecule/metal functional interfaces such as switching devices and quantum computing devices.

    In this work, the design, synthesis, and single-molecule conductance of ethynyl- and butadiynyl-ruthenium molecular wires with thioether anchor groups [RS=n-C6H13S, p-tert-Bu−C6H4S), trans-{RS−(C≡C)n}2Ru(dppe)2 (n=1 (1R), 2 (2R); dppe: 1,2-bis(diphenylphosphino)ethane) and trans-(n-C6H13S−C≡C)2Ru{P(OMe)3}4 3hex] are reported. Scanning tunneling microscope break-junction study has revealed conductance of the organometallic molecular wires with the thioacetylene backbones higher than that of the related organometallic wires having arylethynylruthenium linkages with the sulfur anchor groups, trans-{p-MeS−C6H4-(C≡C)n}2Ru(phosphine)4 4n (n=1, 2) and trans-(Th−C≡C)2Ru(phosphine)4 5 (Th=3-thienyl). It should be noted that the molecular junctions constructed from the butadiynyl wire 2R, trans-{Au−RS−(C≡C)2}2Ru(dppe)2 (Au: gold metal electrode), show conductance comparable to that of the covalently linked polyynyl wire with the similar molecular length, trans-{Au−(C≡C)3}2Ru(dppe)2 63. The DFT non-equilibrium Green's function (NEGF) study supports the highly conducting nature of the thioacetylene molecular wires through HOMO orbitals.

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

    Electrically conductive molecular junctions are highly desirable components for applications in future molecular-scale electronic circuits. Here, we demonstrate an electrically conductive hybrid molecular junction that consists of Au-S and Au-πbindings using a sumanene derivative with three phosphine-sulfide anchoring groups at the periphery of the sumanene backbone. The molecular junction was prepared between the Au electrodes by the scanning tunneling microscopy-based break junction method. The three anchoring groups and the sumanene backbone in the junction form the Au-S chemical bonds and Au-πdirect bonds, respectively. The Au-S chemical binding immobilized the molecule on the Au electrode and provided the high mechanical stability of the junction, while the direct Au-πbinding led to the large metal-molecule electric coupling and high electronic conductance of the molecular junction. This study analyzes the molecular design of the electrically conductive molecular junctions based on the hybrid binding groups.

    Palladium-bearing intermetallic electride as an efficient and stable catalyst for Suzuki cross-coupling reactions
    <title>Abstract</title>Suzuki cross-coupling reactions catalyzed by palladium are powerful tools for the synthesis of functional organic compounds. Excellent catalytic activity and stability require negatively charged Pd species and the avoidance of metal leaching or clustering in a heterogeneous system. Here we report a Pd-based electride material, Y3Pd2, in which active Pd atoms are incorporated in a lattice together with Y. As evidenced from detailed characterization and density functional theory (DFT) calculations, Y3Pd2 realizes negatively charged Pd species, a low work function and a high carrier density, which are expected to be beneficial for the efficient Suzuki coupling reaction of activated aryl halides with various coupling partners under mild conditions. The catalytic activity of Y3Pd2 is ten times higher than that of pure Pd and the activation energy is lower by nearly 35&#37;. The Y3Pd2 intermetallic electride catalyst also exhibited extremely good catalytic stability during long-term coupling reactions.

    Characteristic fast H- ion conduction in oxygen-substituted lanthanum hydride
    Fast ionic conductors have considerable potential to enable technological development for energy storage and conversion. Hydride (H−) ions are a unique species because of their natural abundance, light mass, and large polarizability. Herein, we investigate characteristic H− conduction, i.e., fast ionic conduction controlled by a pre-exponential factor. Oxygen-doped LaH3 (LaH3−2xOx) has an optimum ionic conductivity of 2.6 × 10−2 S cm−1, which to the best of our knowledge is the highest H− conductivity reported to date at intermediate temperatures. With increasing oxygen content, the relatively high activation energy remains unchanged, whereas the pre-exponential factor decreases dramatically. This extraordinarily large pre-exponential factor is explained by introducing temperature-dependent enthalpy, derived from H− trapped by lanthanum ions bonded to oxygen ions. Consequently, light mass and large polarizability of H−, and the framework comprising densely packed H− in LaH3−2xOx are crucial factors that impose significant temperature dependence on the potential energy and implement characteristic fast H− conduction.

    Triptycene Tripods for the Formation of Highly Uniform and Densely Packed Self-Assembled Monolayers with Controlled Molecular Orientation
    When employing self-assembled monolayers (SAMs) for tuning surface and interface properties, organic molecules that enable strong binding to the substrate, large-area structural uniformity, precise alignment of functional groups, and control of their density are highly desirable. To achieve these goals, tripod systems bearing multiple bonding sites have been developed as an alternative to conventional monodentate systems. Bonding of all three sites has, however, hardly been achieved, with the consequence that structural uniformity and orientational order in tripodal SAMs are usually quite poor. To overcome that problem, we designed 1,8,13-trimercaptomethyltriptycene (T1) and 1,8,13-trimercaptotriptycene (T2) as potential tripodal SAM precursors and investigated their adsorption behavior on Au(111) combining several advanced experimental techniques and state-of-the-art theoretical simulations. Both SAMs adopt dense, nested hexagonal structures but differ in their adsorption configurations and structural uniformity. While the T2-based SAM exhibits a low degree of order and noticeable deviation from the desired tripodal anchoring, all three anchoring groups of T1 are equally bonded to the surface as thiolates, resulting in an almost upright orientation of the benzene rings and large-area structural uniformity. These superior properties are attributed to the effect of conformationally flexible methylene linkers at the anchoring groups, absent in the case of T2. Both SAMs display interesting electronic properties, and, bearing in mind that the triptycene framework can be functionalized by tail groups in various positions and with high degree of alignment, especially T1 appears as an ideal docking platform for complex and highly functional molecular films.

    Enhanced Catalytic Ammonia Synthesis with Transformed BaO
    © 2018 American Chemical Society. We report that a simple mixture of BaO and CaH2 powders with ruthenium nanoparticles acts as an effective heterogeneous catalyst for low-temperature ammonia synthesis with a very small activation energy (41 kJ mol-1). The high catalytic performance of this material is not due to either the original CaH2 or BaO particles but to BaO transformed by reaction with CaH2. The transformed BaO contains BaH2, a stable and strong electron-donating material that facilitates a reversible hydrogen storage-release reaction and significantly enhances electron donation to Ru, which results in high catalytic performance.

    Controlling stacking order and charge transport in -stacks of aromatic molecules based on surface assembly
    Here, we report a facile procedure based on surface self-assembly for controlling the π-π stacking order and relevant rectified charge transport properties in stacks of aromatic molecules on a single-molecule scale. A high rectification ratio of 10 was achieved and the rectification direction was uniquely determined by the controlled stacking order of the aromatic molecules on the graphene layers of HOPG.

    "Doping" of Polyyne with an Organometallic Fragment Leads to Highly Conductive Metallapolyyne Molecular Wire
    Exploration of highly conductive molecules is essential to achieve single-molecule electronic devices. The present paper describes the results on single-molecule conductance study of polyyne wires doped with the organometallic Ru(dppe)2 fragment, X - (C≡C)n - Ru(dppe)2 - (C≡C)n - X. The metallapolyyne wires end-capped with the gold fragments (X = AuL) are subjected to single-molecule conductance measurements with the STM break junction technique, which reveal the high conductance (10-3-10-2 G0; n = 2-4) with the low attenuation factor (0.25 Å-1) and the low contact resistance (33 kω). A unique "'doping'" effect of Ru(dppe)2 fragment was found to lead to the high performance as suggested by the hybrid density functional theory-nonequilibrium green function calculation.

    Multi-Scale, Multi-Physics Approach for Solid Oxide Fuel Cell Anode Reaction
    © The Electrochemical Society. The electrode performance in solid oxide fuel cell depends both on electrode materials and microstructure. Therefore, it is important to breakdown the complexity of multi-physics in the porous electrode into processes in different scales. To clarify the multi-physics toward better electrode design, the use of both the advanced measurement and the simulation techniques is inevitable. For this purpose, we have taken the combined top-down and bottom-up approaches. In this manuscript, we discuss the practical issues in multi-scale, multi-physics simulation, focusing on the local activity of Ni-YSZ anode.

    First principles study on electronic structures of Ni/H/ZrO2 triple phase boundary
    We have investigated the electronic structures of Ni/H/ZrO2 triple phase boundary (TPB) from first principles. For this purpose, we constructed a novel computational model for the TPB having a point contact of a Ni-tip and ZrO2(111) surface. We examined several locations of the tip with respect to the ZrO2(111) surface, and found that the fee location of the Ni-tip is the most stable point contact TPB. The projected density of states (PDOS) of the apex Ni atom of the point contact TPB shows a large and sharp peak at 0.5 eV above the Fermi level. Such a large peak, on the other hand, is not seen in Ni(111) surface without Ni protrusions. We also revealed that the adsorption of hydrogen atom at the Ni-tip leads to a wider peak of PDOS of the apex Ni atom. The change in the shape of the PDOS suggests that the adsorption of hydrogen atom at the Ni-tip will alter the reactivity of the TPB of Ni-tip/ZrO2(111). ©The Electrochemical Society.
