  Study of the electronic structure of Au–V bimetallics using X-ray photoelectron spectroscopy (XPS) and X-ray absorption near-edge structure (XANES)

  摘要：

  Core-level binding energy shifts and valence band behaviour for Au-V intermetallic compounds have been studied with X-ray photoelectron spectroscopy (XPS) and X-ray absorption near-edge structure (XANES). It is found that both the Au 4f and V 2p core levels exhibit a positive binding energy shift, relative to the pure metals. These results can be explained with the charge compensation model (Watson et al., Phys. Rev. B4 (1971) 4139): there is an increase in the number of sp-like conduction electrons accompanied by a decrease in the d-electron count at the Au site resulting in a small net charge flow onto the Au site in accord with electronegativity and electroneutrality considerations. Au L-edge X-ray absorption near-edge structures (XANES) provide direct evidence for d-charge depletion at the gold site confirming the XPS results. V g-edge XANES indicate d-charge depletion at the V site, as well. These results are compared with those for Au-Ti and Au-Ta alloys. (C) 1999 Published by Elsevier Science S.A.
