Abstract
We present the Fermi surface map of p(2×2)O/Mo(110) at room temperature. Changes with respect to the clean surface are discussed. Three surface-state contours (‘hole pockets’) that exist on the clean surface are found to persist on the oxygen-covered surface with slightly changed volumes. The large ‘electron pocket’ shows no significant shift. In combination with a previous electron energy-loss spectroscopy experiment measuring the surface phonon dispersion curves, these data put into question the recently postulated driving force for stabilizing the p(2×2) superstructure in the low-coverage regime.
