Open publisher page 6 citations

Abstract

The dispersions of the sp bands in Ag-Au(111) superlattices are calculated. The calculation employs the nearly free-electron approximation for the wave functions within the Ag and Au layers. A one-band model for the superlattice band structure is developed and applied to the present system. This results in a simple analytic formula for the band dispersions of the superlattice geometry. The calculated band dispersions are in good agreement with experimental results determined previously by photoemission spectroscopy.
