Abstract

We give a survey of our recent results concerning the theory of the inelastic electron scattering by surfaces of solids with an account of both the spatial dispersion of the dielectric response and of the structure of the near-surface region. The method is based on the analytical properties of the dielectric response of the semi-infinite systems as a function of the wave-vector variable q. The latter properties have a close analogue in the analysis of the dielectric function ε(ω) of the bulk solids as a function of the frequency variable ω, but they are specific for semi-infinite systems. The relations similar to these of Kramers-Kronig are obtained in q variable. The application of the method to metals, solid superlattices, and uniaxial crystals are presented and discussed.
