    Abstract

    The full surface phonon dispersion curves of graphite (0001) over the entire energy region and the entire Brillouin zone along the ΓM direction have been determined for the first time by using electron energy loss spectroscopy. These dispersion curves agree well in the appropriate limits with bulk values measured by infrared spectroscopy and neutron scattering. The intraplanar interactions in the topmost basal plane appear to be the same as those in the bulk.
