Abstract
We describe a new method for calculating two-dimensional energy bands in thin films. The method has the advantage that the potential varies continuously between film and vacuum regions and may even be made self-consistent. A band calculation has been performed for a 13-layer (1,0,0) Li film. We display graphs of the charge density and of the wave function of a surface state found in the (½, ½, 0) energy gap.Keywords
