Abstract
We demonstrate the possibility of using angle-resolved photoemission from valence levels to gain overlayer site geometry information. To do this we utilize and discuss polarization effects and photoexcitation cross-section effects (as a function of the photon energy). To illustrate the application of the technique we have studied Pd overlayers on Nb(110) and conclude that the Pd(110) overlayer has a hollow-site geometry.Keywords
