Abstract
Photoemission of the Sb-covered Si(001) surface showed that the Fermi-level position crosses the conduction-band minimum of Si for Sb coverages approaching a 1-monolayer saturation limit. Momentum-resolved photoemission of the Sb-saturated Si(001) surface revealed the existence of an occupied initial state located near the conduction-band minimum. The metallic character of the surface is shown to be indicative of degenerate doping in the near-surface region.
