Özet

Scanning tunneling spectroscopy was used for investigating the surface electronic structure of (2 × 1) and c(4 × 2) domains on Ge(001). A UHV system with a constant base pressure was applied at room temperature for the investigations. The presence of a metallic state on the (2 × 1) domains, which was absent on the c(4 × 2) domains, was indicated by the measured surface densities of states. The flip-flop dimers that constituted the (2 × 1) domains was responsible for this metallic state which was observed only in integral measurements.
