Surface lattice dynamics of thep(3×1)−Ag(110) system

  • G. Bracco
  • R. Tatarek


We present a detailed study of the lattice dynamics of thep(3×1)O-Ag(110) surface to determine the structural changes of the substrate upon oxygen chemisorption. The lattice dynamical calculations are carried out using central forces with nearest-neighbour interactions and assuming different surface structures. The limits of the models are discussed. A comparison with the dispersion curves measured along two azimuthal directions by means of energy-resolved He-atom scattering unambiguously shows the reconstruction of the silver substrate.
