Abstract
Shifts in the core-level binding energies of surface atoms relative to bulk atoms which show a dramatic dependency on surface crystallography have been observed. Surface-atom core-level emission intensities are shown to give direct information on the number of surface atoms, while binding energies give information on the surface-atom coordination number. These data show that the reconstructed Ir(100)-(5×1) face is described by a compressed hexagonal monolayer.Keywords
