Abstract
The phase shift upon reflection of a valence Bloch electron in Ag at the Ag/Cu(111) interface is determined by angle-resolved photoemission. It shows a singularity at the band edge of Cu, allowing a determination of the substrate band-edge energy. The singular behavior is shown to be a characteristic interfacial property. A simple-model calculation reproduces the main features of the data. DOI: http://dx.doi.org/10.1103/PhysRevB.40.5845 © 1989 The American Physical SocietyKeywords
