Photoemission via bloch states and evanescent band gap states for Cu(110)

Abstract

Normal emission photoelectron spectra from Cu(110) using polarized synchrotron radiation (hv < 35 eV) can be explained with a direct transition model using realistic final state bands. Prominent surface photoemission via evanescent final states is observed in the large X′5-X1 conduction band gap. Accurate valence band eigenvalues at K and X have been determined. © 1979.
