Quantitative Interpretation of Auger Lineshapes and Electron/Photon Stimulated Desorption
Abstract
This project has involved a quantitative theoretical interpretation of electron spectroscopic data with a view toward elucidating the chemical environment and electronic structure of atoms in the bulk and adsorbed on solid surfaces. Many-body effects, such as shake satellites, initial core hole screening, and final state hole-hole correlation, etc., have been examined and found to have significant effects on the spectral lineshapes. We have more recently examined electron spectroscopic data for the high temperature superconductors, and for chemisorbed species on metals. Electron/photon stimulated desorption (ESD/PSD) was also of interest. Here, an interpretation of spectroscopic data and comparison with PSD spectral yields was very helpful in obtaining an understanding of the image charge, surface resonances, polarization, and the role of many-body interactions in the desorption mechanism itself.
