Abstract

In the LCAO approximation applied to a non degenerate band, we calculate surface states for several surfaces of cubic lattices. The variation of the potential due to the surface is assumed to be localized in the surface plane and is calculated self-consistently to satisfy the Friedel sum rule. For each case the position, the number and the occupation of surface bound states are studied as their extension into the bulk. The results may roughly be applied to the transition metals.
