Surface Vibrations and (2x1) Superstructures on FCC(110) Metal Surfaces.

Abstract

Electron energy loss spectra are presented for a number of adsorbate overlayers which form (2x1) superstructures on the fcc(110) surface of Nickel and Copper. These include (2x1) structures of H, N2, CO, and O. Lattice dynamical slab calculations are used to analyze the vibrational properties observed in the loss spectra which result from symmetry selection rules for dipole activity of the surface phonons. The calculated spectral densities, together with the symmetry selection rules, are used to analyze proposed models for the adsorbate overlayer structures.
