Graphite, Graphene and Relativistic Electrons

Abstract: The recent synthesis of graphene (a single layer of
graphite) has uncovered a fountainhead of astonishing electronic properties that
are linked to the emergence of a new class of quasiparticles, Dirac-fermions,
whose properties are governed by quantum-relativistic dynamics. I will describe
scanning tunneling spectroscopy (STS) and transport experiments that provide
access to these quasiparticles. Our findings include the direct observation of
Landau levels of Dirac-fermions, evidence of the coexistence of massless and
massive Dirac-fermions on the surface of graphite and the observation of induced
superconductivity in single layer graphene.
