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 Al110 and the Fe111 surfaces are now reported. The resonance is observed on Fe but not on Al.
