Abstract

Quantum-well states have been observed with angle-resolved photoemission for Ag overlayers with thicknesses up to 40 monolayers epitaxially grown on Au(111). These states are observed within an energy window of 1 eV. The complementary system, Au on Ag(111), exhibits no such states. The results can be explained in terms of the band-structure mismatch between Au and Ag. The coherence length of the states and quasibound quantum-well resonances will be discussed.
