Abstract
We present self-consistent pseudopotential calculations of both surface and image potential states on simple metal surfaces: Li(110), Na(110), Be(0001), Mg(0001), Al(100), and Al(111). The local density approximation (LDA) is used to describe the one-electron potential inside the film and in the surface region. In the vacuum space (at z>zim) the LDA potential is replaced by the image potential. A one-dimensional potential proposed recently is constructed for 14 simple and noble metal surfaces. By using this model potential we study wave functions and binding energies of the image states and also image plane position trends for these metal surfaces.
