Study of Electron States of Solids by Techniques of Electron Spectroscopy
Presented at the Symposium on the Electronic Structure and Bonding in Solids, 183rd National Meeting, American Chemical Society, held in Las Vegas. Nevada, March 30-31, 1982.
Commuincation No. 181 from the Solid State and Structural Chemistry Unit.
Studies of valence bands and core levels of solids by photoelectron spectroscopy are described at length. Satellite phenomena in the core level spectra have been discussed in some detail and it has been pointed out that the intensity of satellites appearing next to metal and ligand core levels critically depends on the metal–ligand overlap. Use of photoelectron spectroscopy in investigating metal–insulator transitions and spin-state transitions in solids is examined. It is shown that relative intensities of metal Auger lines in transition metal oxides and other systems provide valuable information on the valence bands. Occurrence of interatomic Auger transitions in competition with intraatomic transitions is discussed. Applications of electron energy loss spectroscopy and other techniques of electron spectroscopy in the study of gas-solid interactions are briefly presented.
