Chapter 8 - The structure of surface alloy phases on metallic substrates

摘要: This chapter explains the structure of surface alloy phases on metallic substrates, discusses a series structurally well characterized alloys formed metal substrates by (or near metallic) Adsorbates, and compares measured interatomic distances rumpling amplitudes with estimates these parameters to be expected basis simple hard-sphere picture. The groups systems according some common physical problems or characteristics, provide clear contrast such phenomena, but then reviews issue effective atomic radii in general. structural methods used individual investigations are varied include diffraction methods—quantitative low energy electron (LEED) x-ray (SXRD)—local interference methods—scanned-energy mode photoelectron diffraction, PhD, angle-scan XPD, extended absorption spectroscopy—and various forms ion scattering at high energies. concentrates only quantitative results determinations, although it illustrates overall methodology referencing from several different applied first group phases.
