The metal-to-oxide transition on the Mo(100) surface has been studied by monitoring surface polarizability using X-ray photoelectron spectroscopy (XPS) measurements of physisorbed xenon. It was found that complete oxidation occurs over the narrow coverage range of 1.0-1.4 monolayers of oxygen. Furthermore, the surface is heterogeneous and most likely an island structure in this coverage range.
