Description

Abstract In recent years, high-resolution electron-energy-loss spectroscopy (EELS) has been successfully applied to the study of vibrational properties of surfaces and interfaces of materials having a layered structure. At the same time the theory of long-wavelength electromagnetic properties of surfaces and interfaces and their role in the inelastic scattering processes of electrons at the surface has also developed to a point where detailed quantitative comparisons between experimental and theoretic... Title of program: HREELS of multilayers Catalogue Id: ABTI_v1_0 Nature of problem The computer program allows to calculate the electron-energy-loss spectrum of an arbitrary plane-stratified medium for low-energy electrons specularly reflected at the surface of the target. A dielectric approximation is used to characterize the response of the target material to the long-ranged coulomb field of the impinging electrons. Periodic superlattices can be considered as well as any arbitrary stacking of layers onto a thick substrate. In the later case, the substrate is allowed to be a ...
