  The interaction of graphene with metallic substrates reveals phenomena and
properties of great relevance for applications in nanotechnology. In this
review, the vibrational characterization by means of various inelastic
scattering spectroscopies are surveyed for graphene epitaxially grown on metals
and transition carbides. In particular, the manifestations of electron-phonon
interaction, such as Kohn anomalies, the evaluation of elastic properties and
the nanoscale control of phonon modes are presented and discussed.
