Sažetak
We have performed ab initio density functional ca1culations of 1 to 3 monolayer films of silver on a Pd(111) surface. Due to the similarity of the lattice constants, silver layers grow in register with the substrate. We have in particular studied the electronic structure, and the formation of quantum well (QW) states in the overlayer films. The s states of silver which are close to the Fermi level hybridize strongly with palladium states, while the d states at binding energies around 4 e V do not have corresponding palladium states, at least around the centre of the surface Brillouin zone, and can form QW states. This is in agreement with recent photoemission experiments on such systems. We discuss the predictions of our calculations for a range of film thicknesses and angles in angularly resolved photoemission.
