Abstract
The understanding of the electronic structure of transition- and noble-metal clusters has been advanced recently by complementary experimental and theoretical research. This lecture will reflect both aspects. On the theoretical side we will examine some of the techniques of calculation including extended Hückel, CNDO, and Hartree-Fock as well as perturbation theory. These methods will be applied to problems of cluster geometry, charge distribution, ionization potential, and density of states in order to compare with results for infinite and semi-infinite analogues. Several quite different approaches have shown encouraging agreement in the properties of small clusters, which are significantly different from those of the bulk. We will also consider in a simplified fashion how a model substrate can alter the properties of metal clusters. On the experimental side we will discuss photoemission (UPS and XPS) data that can be compared with theoretical data. In the evaporated-particle model systems considered, small-cluster data are at significant variation with bulk data. In addition, some UPS experiments attempting to understand the range of metal particle/adsorbate interactions will be discussed.
