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
From many experimental studies, a localized intrinsic acceptor level is assumed to exist at about 0.2 eV above the valence band edge in -rhombohedral boron. The acceptor level has been tentatively originated from the unoccupied intracluster bonding level split away from the valence band due to the d
