Abstract

Proceeding from the self-consistent HFS-potentials[1] of the ions Sc + and N −, a quasiselfconsistent calculation of the band structure of ScN was carried out via the APW-method. The energy eigenvalues and the wave functions for an equivalent of 256 k-points in the first Brillouin zone were calculated using the full Slater exchange potential. According to these calculations, ScN is a semiconductor with a band gap of about 0·1 eV and possesses a partially ionic character.
