Energy Spectra of Inelastically Scattered Electrons and LEED Studies of Tungsten

Abstract

Energy distributions of the electrons inelastically scattered from the tungsten (110) surface for primary energies of 50–350 eV have been obtained using a modified LEED system. The information contained in these secondary electron energy distributions has been coupled with LEED patterns, thereby affording a more complete understanding of the electron scattering processes in the low‐energy range. The physical processes contributing to the characteristic losses and other features observed in the energy spectra are discussed, and the expected behaviors are compared with experimental observations. LEED patterns are used to characterize sample‐surface conditions.
