Effect of Sodium Atom Adsorption on the Electronic Structure of a Gold Film

The electronic structure of a gold film deposited on W was studied during the adsorption of sodium atoms. An analysis of the photoemission spectra from the valence band and core levels of Au 4 f and Na 2 p upon synchrotron excitation in the photon energy range of 80–600 eV showed that Na adsorption...

Description
Summary:The electronic structure of a gold film deposited on W was studied during the adsorption of sodium atoms. An analysis of the photoemission spectra from the valence band and core levels of Au 4 f and Na 2 p upon synchrotron excitation in the photon energy range of 80–600 eV showed that Na adsorption leads to the formation of Na x Au y intermetallic compounds of various stoichiometry under the Na monolayer.
