    Notes: Abstract We develop a theory of low energy electron loss spectroscopy of vibrational modes of molecules adsorbed on metal surfaces. Differential and total cross sections are calculated in the Distorted Wave Born Approximation, assuming i) strong elastic scattering on the metal surface, ii) direct electron-molecule interaction via the electric dipole field associated with the molecular vibration. The angular distributions are calculated and discussed for molecules adsorbed at various distances above the metal surface and for several electron energies and impact angles. The influence of electronic screening of dipolar oscillations is discussed and the consequences of the classical induced “image” dipoles are explored. It is shown that the “metal surface selection rule” known in IR spectroscopy is only approximately valid in electron scattering. Finally, we give numerical estimates of the inelastic scattering cross sections for the stretching vibrations of CO molecule adsorbed on transition metal surfaces, in reasonable agreement with experiments.

    The properties of a parallel-plate capacitor in a plasmon model (1979)
    Springer
    The European physical journal 33 (1979), S. 145-154 
    Details
    ISSN: 1434-6036

    Topics: Physics
    Notes: Abstract The problem of a general static-charge distribution interacting with a parallel-plate capacitor is solved in a plasmon model, i.e. in the long-wavelength approximation. The relevant physical quantities (potential, electric field, polarisation, etc.) are decomposed into two parts with respect to surface and bulk plasmon contributions. The microscopic corrections due to the Landau damping enter through both surface and bulk plasmon cut-off wave vectors. Two problems are discussed in detail: the screening of a point charge and the properties of a charged capacitor (image potential, capacitance, etc.).
