Geometric Structure and Surface Vibrational Resonances: The BCC Fe(111) Surface.

Abstract

The influence of strong multiple interplanar forces is shown to give rise to a new class of surface vibrational resonances on metal surfaces as a result of higher harmonic terms in the bulk phonon dispersion relations. This effect is illustrated with the bcc F3(111) surface where a surface resonance is observed at 21 meV by high resolution electron energy loss specatroscopy, in excellent agreement with precdictions by surface lattice dynamics calculations.
