Abstract

We report on a low energy, reflection electron energy loss spectroscopy study of the (0001) surface of graphite. Angle dependent structures are observed in an intense loss continuum over the energy loss range 0–1.4 eV. Electronic excitations across the Fermi level in the semimetallic band structure are shown by calculation to produce a surface response function which, when combined with the kinematic factor in the dipole scattering probability function, gives rise to these structures.
