摘要：

We have exploited angle-resolved one-photon photoemission, two-photon photoemission, and spot-profile analysis of low-energy electron diffraction to monitor the influence of surface morphology on the occupied and empty surface states observed at Gamma on Cu(111). Surface morphology changes were induced by homoepitaxial growth of Cu on Cu(111). A simple model of electron localization on terraces successfully explains energy shifts and linewidth broadening of both surface states. Obviously, surface states may be used as sensitive probes of terrace-width distributions and other structural properties.
