Angle Resolved Auger Electron Spectroscopy: An Alternate Tool for Identifying Electronic Excitation Processes in Solids
Abstract
Angle resolved Auger electron spectroscopy (ARAES) is shown to be a useful tool for obtaining unique electronic structure information and identifying satellite excitation processes in solids. Although relatively unexplored, ARAES is an attractive tool which may complement the more conventional energy resolved AES. The ARAES method is successful because the diffraction patterns exhibited in ARAES at fixed energy are strongly dependent on the l-wave of the emitted electron and its magnetic alignment, and each Auger process is generally dominated by a different single l-wave. Potential applications for elucidating satellite excitation processes (resonant excitation, shakeup/shakeoff, and backscattering), one- and two-center decay processes, and electronic structure (directional valence bonds and orbital magnetic moments) at surfaces are discussed.
