Abstract The adsorption properties of Au on β-SiC(111) surfaces are studied using the charge self-consistent extended Huckel theory. The intermixing between Auatom and, β-SiC could happen only on the Si-terminated (111) surface. In the case of Si-terminated, there is a intrinsic surface state in the energy gap, and the Fermi energy is pinned at this surface state. But in the case of C-terminated, the surface state exists near the top of the valence band.
