ABSTRACTWe have studied the valence band and surface-core-level states for laser-annealed, thermally-annealed, and cleaved Ge(111) and Si(l11) surfaces with high resolution photoelectronspectroscopy using synchrotron radiation. For the annealed surfaces we find two surface states near the top of the valence band as well as characteristic surface core level spectra. These indicate the existence of a common local bonding geometry for all these surfaces. We observe that the (1 × 1) and cleaved (2 × 1) surfaces are not related as recently reported for Si.

Using high-resolution core-level photoemission with synchrotron radiation, we observed two suboxide states on the Nb(001) surface, which was heated in 1×10-6 Torr O 2 for several hours and then annealed several times at high temperatures in an ultrahigh-vacuum condition. These suboxide states were identified as Nb2O and NbO from the Nb3d5/2 core-level photoemission spectra. The relative amounts of these suboxide states varied with the annealing temperature, showing that at progressively higher temperatures more oxygen-deficient oxides were produced. Meanwhile, LEED patterns of the complex superstructures of the oxidized surfaces also changed. Many of these findings are analogous with other oxidized refractory metals.

Binding Energy Shift

Copper adsorption on Ru(0001) has been studied by synchrotron radiation. The clean Ru 3d 5/2 spectra were found to consist of two components with a binding energy shift of 400 meV. The component with the lower binding energy represents the first layer of ruthenium atoms. Adsorption of copper gives rise to core level shifts of the Ru 3d 5/2 components, which were studied as a function of Cu coverage. Experiments were carried out with copper coverages varying from the submonolayer range up to two monolayers of copper. The binding energy of the Cu 2p 3/2 level was measured by X-ray photoemission spectroscopy.
