Abstract
An original one-dimensional semi-infinite approach with a realistic po tential, obtained from first-principle slab calculations, is presented and applied to study image resonances at clean Al(001) and Al(001)+Na (2x2) surfaces. The obtained results, being in reasonable agreement wi th experimental data, are compared with those of Silkin and Chulkov [P hys. Solid State 36 (1994) 404]. The presence of the ''thin film'' sta te, incorrectly considered by Silkin and Chulkov as the (n=0) image st ate, is discussed. (C) 1997 Elsevier Science B.V.
