Abstract
We report a Cu 2p X-ray absorption spectroscopy (XAS) study of Cu pseu domorphic epilayers grown on Ag(001) as a function of the Cu coverage from the sub-monolayer up to similar to 3.6 ML. The thus-probed Cu 3d unoccupied distribution of states local to the Cu sites is found to ex hibit a strong similarity in the shape with respect to bcc ultrathin C u films grown on Fe(001). In addition, the spectra change as the overl ayer is progressively increased thereby reflecting the evolution of th e structural properties.
