Periodic density functional theory was used to investigate the stability and electronic structures of precious-metal atoms in the vicinity of LaFe(1-x)M(x)O(3) (M = Pd, Rh, Pt) perovskite catalyst surfaces. It was found that the surface segregation o

A potential of superconductivity of pure graphite has been theoretically examined. At normal pressure, the carrier concentration is too low to exhibit superconductivity. On applying pressure, the band dispersion along the c -axis is significantly enh

Use of a high-pressure process is proposed for synthesizing highly doped semiconductors. Working on a real example in a recent experiment by Ekimov on B-doped diamond synthesis, a theoretical investigation has been made of an efficient doping method.

We propose materials design of CuAlO 2 -based dilute magnetic semiconductors (DMSs). The electronic structures and the magnetic properties of CuAlO 2 -based DMSs are calculated by using the Korringa–Kohn–Rostoker method combined with the coherent

Luminescent properties of GaN and AlN based semiconductors containing rare earth metals of Gd and Dy are studied. Cathodoluminescent spectra from AlGdN show a clear and sharp peak at 318 nm following LO phonon satellites. Photoluminescence spectra fr

We propose new-type ferromagnetic semiconductors based on CaO and K2S without any transition metal elements. These materials show transparent and half-metallic ferromagnetism if the deep-impurity-band width (W) induced by doping of C, N, Si, or Ge im

To clarify the anisotropic gap behavior of YNi 2 B 2 C, energy band structures and Fermi surfaces are calculated by using an FLAPW method. The de Haas-van Alphen frequencies and the cyclotron masses are compared with the experimental results. The com
