From LEED to MULSAM

This account gives an outline of the work done in the Department of Physics , University of York since 1965, The Surface Physics Group has been particu larly active in the development and application of electron probes of solid surfaces with strong emphasis upon low-energy electron diffraction and sca nning electron microscopy using Anger electrons to form images. A scanning Auger microscope using multi-imaging (MULSAM) has been particularly fruitfu l for the study of a variety of heterogeneous materials. Examples are given of the application of MULSAM to the minimization of topographic contrast a rtefacts, to the study of multilayers of magnetic materials, to the charact erization of very rough PtRh catalyst surfaces, to the interpretation of th e shapes of electron spectra and to the angular dependence of both Auger el ectron and energy-dispersive x-ray signals.
