Electron spectroscopy of disordered metal alloys

We review the contribution that electron spectroscopy has made to the understanding of the electronic structure of disordered metal alloys. In this review we consider the results of direct studies of the conduction band densities of states using photoelectron techniques and indirect studies of the correlation energies, charge transfers and electron screening through indirect probes combining photoelectron and Auger spectroscopies. It is clear that results obtained from a variety of approaches have made major contributions to the development of both empirical models and first principles treatment of alloy electronic structure.
