Abstract
MAPW band-structure calculations for TiC have been performed with three crystalline potentials determined by different methods: the first (V1) was constructed by modified atomic wavefunctions, the second (V2) resulted from self-consistent APW band-structure calculations, and the third (V3) was formed from MAPW wavefunctions. While potentials V1 and V2 are in muffin-tin form, V3 has angular dependence. The computational methods are summarized and the resulting band structures discussed especially with regard to their dependence on the different potentials.
