Abstract

As synchrotron radiation users around the world know, photoelectron spectroscopy using either ultraviolet (UV) or X-ray photons is a common technique for studying materials. Photoelectron spectroscopy is a powerful technique because it can directly probe, via the measurement of photoelectron kinetic energies, orbital and band structure in valence and core levels in a wide variety of samples: atoms, molecules, clusters, solids, surfaces and adsorbates. The technique becomes even more powerful when it is performed in an angle-resolved mode, where photoelectrons are distinguished not only by their kinetic energy, but by their direction of emission as well. Determining the probability of electron ejection as a function of angle is an excellent probe of the different quantum-mechanical channels available to any photoemission process, because it is sensitive to phase differences among these channels. As a result, angle-resolved photoemission has been used successfully for many years to provide stringent tests of our understanding of basic physical processes underlying gas-phase and solid-state interactions with radiation, and also as a tool to probe physical and chemical structure in solids and surfaces.
