Abstract

A brief survey of some of the recent literature on elastic and inelastic low-energy electron diffraction (LEED) from solids is given, Our present knowledge of the electron-solid force law is discussed. The state of the art of theoretical model calculations of LEED intensity profiles is described and compared with the current status of experimental measurements. Prescriptions for obtaining surface crystallographic information directly from the experimental LEED profiles are described. The use of inelastic LEED as a spectroscopic probe of the electronic excitations of the surface region of solids is also mentioned.
