Abstract
We present photoemission results for thin overlayers of Pd grown epitaxially on Au(111). The development of the Pd electronic structure near the Fermi energy is examined as a function of overlayer thickness. It is observed that the density of states at the Fermi energy is relatively small for the Pd monolayer and that the monolayer does not chemisorb CO at room temperature. We discuss the possible implications of this behavior for recent models of CO chemisorption.Keywords
