Abstract

The energy spectrum and the probability densities of the surface, the image and the quantum well (QW) states of the Ag/Cu(111) system have been calculated function of the thickness of the silver film. The layer by layer energy spectrum and probability densities of this system are obtained as a solution of the Schrödinger equation using the discrete variable representation (DVR). In this equation we have used an analytical one-dimensional model potential derived from the potential of Chulkov et al. [1]. Our calculated energy spectrum and probability densities of the surface, image and QW states present coverage dependence in agreement with the experiments and other calculations of the surface states.
