We present the herringbone structure search (HSS) method to predict the crystal structures of organic semiconductors from molecular structural formulas. The charge transport efficiency of small-molecule organic semiconductors is governed by molecular

A very large enhancement of Raman scattering was observed for WOx nanorods with the {001}CS structure, enabling single-molecule detection of CO molecules adsorbed on WOx nanorods through Raman scattering.

The electronic, lattice, and magnetic properties of CoSb3, Cr-doped CoSb3, and related compound thin films were calculated by using the total energy pseudopotential method. A vacuum region and slab as a thin film were periodically repeated in the sup

We studied thin films of Fe2VAl, Fe2VAl/Si, and a related compound using the total energy pseudopotential method. The internal atoms in a supercell of the repeated slab model were fully relaxed, except for Fe2VAl/Si. The detailed electronic and magne

We present theoretical calculations of the thermoelectric properties of a magnetic semi-conductor CuFeS2. The electrical contributions, namely the Seebeck coefficients, electrical conductances, and electronic thermal conductances, are investigated us

The thermoelectric properties of TiN/MgO surface nanostructures have been determined using first-principles calculations based on the nonequilibrium Green’s function (NEGF) method. Through structural modification of the surfaces at the atomistic le

Enhancing the efficiency of thermoelectric materials has been practiced extensively by either improving the power factor or reducing the lattice thermal conductivity. Magnetism, and the magnetic moment–charged carrier interactions, has been suggest

We developed and implemented a numerical code called SAKE, which stands for (simulation code for atomistic Kohn-Sham equation). We developed it for first-principle electron transport calculations based on density-functional theory and non-equilibrium
