Low-Energy Surface-Phonons on alpha-Quartz (0001)
Résumé
Calculated surface-phonon dispersion curves for a dry, a partly hydroxylated, and a fully hydroxylated alpha-quartz (0001) surface are presented and compared with first low-energy inelastichelium-atom scattering measurements. Qualitative agreement between calculations and the observed Rayleigh-wave dispersion curve is achieved for the dry quartz surface. A signature effect is seen in the calculated phonon dispersion curves for the fully hydroxylated surface.
