Two-dimensional valence-electronic structure of a monolayer of Ag on Cu(001)

Abstract
The metal overlayer system c(10×2)Ag/Cu(001) was studied at coverages near one monolayer with angle-resolved photoemission. The observed spectroscopic features indicate a two-dimensional d-band electronic structure that can be interpreted with the use of a model with planar, hexagonal symmetry in which crystal-field effects dominate over spin-orbit effects.
