Structure-Induced Surface Vibrational Resonances on Metal Surfaces.

Abstract

A new class of surface vibrational resonances are shown to exist on surfaces having a non-monotonic bulk phonon dispersion as the result of their particular geometric structure. These resonances have previously been observed by electron energy loss spectroscopy on the (110) surfaces of Cu and Ni, and analysis based on surface lattice dynamics of measurements on the Al(110) and the Fe(111) surfaces are now reported. The resonance is observed on Fe but not on Al.
