 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.
