THE STRUCTURE AND LATTICE DYNAMICS OF UNRECONSTRUCTED FCC (001) AND (111) METAL SURFACES

Progress in first-principles surface phonon calculation and multiple scattering phonon cross-section calculation has provided a more complete understanding of the localized vibrational modes on unreconstructed metal surfaces. A discussion of some of the new results is given focusing on how the new information resolves earlier difficulties in the interpretation of inelastic He-atom scattering (HAS) and high-resolution electron energy loss spectroscopy (EELS) data on these metal surfaces.
