Abstract

Using the linear muffin-tin orbital method in the atomic sphere approximation (LMTO-ASA), we studied the electronic structure of the Si(111) interface for four different materials: CaF2, NiSi2, CoSi2, and YSi2. We examined how the interface states and Schottky barrier height depend on the interface atomic structure.
