Surface plasma oscillations as a tool for surface examinations
Abstract
The energy spectrum of electrons, inelastically scattered by solids, shows intensity maxima which are due to the excitation of plasma oscillations of the surface of the solid under examination. The study of this phenomenon thus gives information of the surface. The characteristic features of these surface energy losses are resumed (position, thickness- and angular dependence of the loss intensity, coupling dispersion). Recent experiments are described which show the influence of thin coating films on the position and intensity of the surface losses: e.g., oxide films on Mg and Al, Mg film on Al, carbon film on Ag. An appendix resumes the theoretical relations for evaluating the experimental results.
