Abstract

The surface electronic structure of Ge(001) was studied by scanning tunneling spectroscopy. The measured surface densities of states unequivocally reveal the presence of a metallic state on the (2×1) domains, which is absent on the c(4×2) domains. This metallic state, so far observed only in integral measurements, is attributed to the flip-flopping dimers that constitute the (2×1) domains. Our data also reveal a set of previously unresolved surface states, in perfect agreement with published theoretical predictions
