Abstract

We report here the measurements of the energy and dispersion of the surface plasmons on Ag single crystals in UHV using angle-resolved electron-energy-loss spectroscopy. The energy of small-momentum surface plasmons depends upon crystal face and, for Ag(110), upon crystal orientation. The differences in the energies of the surface plasmons, which cannot be explained by a jellium model, are discussed in terms of the contributions to the dielectric response from surface states and truncated bulk band states.
