摘要：
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 Schrodinger 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. W. 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.
