Graphene: QED and MOSFET on a Pencil Tip

Sankar Das Sarma

University of Maryland

Graphene, a stable rolled out carbon nanotube structure, is a rather amazing two-dimensional system with a chiral linear Dirac like electron-hole band spectrum on the 2D honeycomb lattice of carbon atoms. In this talk I will discuss graphene electronic transport properties by considering electron-impurity, electron-phonon, and electron-electron interactions. Extensive comparison with experimental data will be made throughout the talk with the emphasis on the prospects for graphene as a future transistor material as well as the fundamental aspects of solid state transport of interacting chiral Dirac electrons.
