Rhombohedral boron ( -rh. boron) was doped with V, Cr, Fe, Co, or Zr to investigate the relationship between occupancies of the doping sites and thermoelectric properties. Doping with V or Cr, which preferentially occupy the A 1 sites, produces an increase in electrical conductivity and a negative S

Electron energy-loss spectra of Li-and V-doped -rhombohedral boron ( -r-B) were measured from perfect crystalline areas of 180 nm in diameter. The onset of spectra of Li-doped -r-B was observed at about 1.5 eV, but that of V-doped -r-B was not clearly observed. The volume plasmon peaks of Li-and V-d
The modulated photocurrent method has been applied to pure and vanadium (V)-doped -rhombohedral boron ( -B) with the goal of investigating the di4erence in the distribution of electronic states in the band gap between them. Excitation light intensity dependence of the amplitude and phase shift of ph
