Abstract
We present experimental Fermi contours for surface-localized states on O/Mo(011) and O/W(011). The contours are consistent with the fact that a (2 × 2) superstructure is observed on Mo(011) but not on W(011) through a global Fermi contour instability in which entire orbits are closely coupled by the wave vector of the superlattice. Our results are also consistent with a recently observed sevenfold reconstruction of the (2 × 2) oxygen structure on Mo(011) through a simple Peierls mechanism. We discuss the generality of such behavior in adsorption systems.Keywords
