摘要：

Surface electronic band structure of ZnSe(001)-c(2 x 2) calculated using ab initio methods is compared to angleresolved photoemission data. The experimental photoelectron spectra clearly reveal the surface-induced breaking of the fourfold bulk symmetry. Predicted surface- related features are identified in the experimental data and their origin is determined by comparison with layer-resolved band-structure calculations. (c) 2005 Elsevier B.V.
