Lowhyphen;energy vibrational modes of the monolayer adsorbate CO2/NaCl(001)

摘要

Dispersion curves of surface vibrational modes of monolayer CO2/NaCl(001) have been measured by inelastic He atom scattering along the Ggr;Xazimuth. Eight phonon modes could be followed across almost the entire Brillouin zone. The identification of the modes is discussed based on previously calculated normal mode energies at the zone origin.
