摘要: The first part of this article is a basic introduction to the theory surface collective excitations from macroscopic point view. solution elastic wave equation and Maxwell equations combined with appropriate boundary conditions yields dispersion relations Rayleigh waves polaritons associated plasmons, excitons, optical phonons magnons, respectively. second devoted microscopic A short review various methods used in lattice dynamics serves as an Green’s function vibrations ionic crystals. Finally recent progress spectroscopy by means atom scattering mentioned illustration late achievement theoretical interpretation inelastic spectra.
