摘要：

The linear-muffin-tin-orbital method is used to study the adsorption of a monolayer of Fe atoms on the beta-SiC(100) surface. Adsorption energies of Fe on both Si- and C-terminated (100) surfaces are calculated. It is found that Fe can adsorb on both the Si- and C-terminated (100) surfaces. In the case of a clean Si-terminated surface, the 2p(3/2) core level of the surface Si atoms shifts downward, since the surface Si atom loses more of its electrons than does the bulk Si atom. When a monolayer of Fe atoms adsorbs on this surface, the 2p(3/2) core level shifts upward; this is due to the fact that charge transfers from Fe to the surface Si atom. In addition, the layer projected density of states is also studied.
