摘要：

A simple model is presented for the adsorption of a dense commensurate layer of metal atoms adsorbed on a single crystal substrate. Both the adsorbate and the substrate are modeled as jellium with an appropriate lattice of pseudopotentials. Model calculations give a reasonable order of magnitude for the Gibbs energies of adsorption and for the surface dipole potentials. In agreement with experimental findings absorption is found to be stronger on the more open adsorbate surfaces.
