Low temperature electronic transport properties of graphene

November 7 , 2006

12:00 noon - 1:00 p.m. Grier Room 34-401

Abstract:

Graphene, a single sheet of graphite, is a two-dimensional material which has been long-studied theoretically, but only recently become available to experimentalists. Recent experiments have shown that the electronic properties of graphene are even more remarkable than previously thought. In my talk I will describe the fabrication and characterization of graphene devices, and introduce their basic electronic properties. I will then focus on the fundamental aspects of quantum electronic transport through graphene, which have led, for example, to the discovery of unusual quantizations of the Hall effect or the so-called "minimum conductivity" problem. I will end by showing our recent experiments where we study induced superconductivity in graphene, an observation which elucidates on the quantum coherent properties of electrons in this novel two-dimensional electron gas.
