Abstract
A method which represents surface electronic structure exactly in terms of local functions is tested by applying it to a one-dimensional surface potential. A single four-parameter variational calculation yields continuum and surface-state wave functions for an entire perturbed band. Comparison with exact solutions obtained independently indicates that the calculation is quite accurate.Keywords
