Three-Photon Photoemission from Cu(100): Observation of an Unoccupied Surface State Near Gamma

Abstract

The photon energy dependence has been measured for three-photon photoemission from Cu(100). A narrow resonance (FWHM = 0.02 eV) was observed centered at 2.02 eV photon energy. The resonance can be explained by the presence of an unoccupied surface state near the center of the surface Brillouin zone at gamma and 2.0 eV above EF.
