Abstract / Description:The inelastic electron tunneling spectrum (IETS) of highly oriented
pyrolitic graphite has been measured with scanning tunneling
spectroscopy (STS) at 6 K. The observed spectral features are in very
good agreement with the vibrational density of states of graphite
calculated from first principles. We discuss the enhancement of certain
phonon modes by phonon-assisted tunneling in STS based on the
restrictions imposed by the electronic structure of graphite. We also
demonstrate the local excitation of surface plasmons in IETS, which are
detected at an energy of 40 meV.
