Abstract
A simple dynamical scattering potential for electron diffraction by a free surface of a solid state sample is proposed. A few monoatomic layers parallel to the surface of the scattering sample are treated as a thin film while the other part of the sample is considered as a substrate. The scattering potential of the sample is expressed in terms of the mean square displacement of atoms and the electron density distribution at a scattering surface of the thin film sample. The obtained formula for the scattering potential in special cases leads to results of Dvoriankin’s paper [3]. The proposed surface scattering potential can be used to describe low energy electron diffraction (LEED) as well as high energy electron diffraction (HEED) experiments.
