Vibrational Surface Electron-Energy-Loss Spectroscopy Probes Confined Surface-Phonon Modes
Vibrational Surface Electron-Energy-Loss Spectroscopy Probes Confined Surface-Phonon Modes
The study of surface phonons, collective atomic vibrations localized on the surface of solids, has long been helped by insights from experiments on surface plasmons, their electronic counterparts. A new analysis takes these analogies in the opposite direction, using modern concepts for plasmons to explain current phonon experiments.
