METHOD OF CALCULATING THE ELECTRON-PHONON SCATTERING OF SURFACE ELECTRONIC STATES ON THE (110) SURFACE OF NOBLE METALS

摘要

A theoretical method of calculating the electron-phonon scattering of electron and hole excitations on the (110) surface of noble metals is described in detail. The method is based on a description of the electronic surface structure by two-dimensional model pseudopotential. As an example, the electron-phonon interaction parameters for the surface states and image potential states localized in the (Y) over bar -gap are calculated for the Pd(110) surface. The electron-phonon coupling parameter. calculated in two surface states differs by several times owing to different localizations of the states. The parameter. for the image potential states is rather small.
