Abstract
Two qualitatively different structural models are currently popular for the stable 2×1 superstructure characteristic of the Si(100) surface. We report the results of realistic self-consistent calculations of the electronic spectrum for both. Comparison with uv photoemission data clearly favors the pairing model over the vacancy model. Our results on surface Fermi-level pinning and bond saturation support this conclusion.Keywords
