Phys. Rev. Lett. 98, 076602 (2007) [4 pages]Quantum Transport of Massless Dirac FermionsReceived 22 June 2006; published 14 February 2007 Motivated by recent graphene transport experiments, we undertake a numerical study of the conductivity of disordered two-dimensional massless Dirac fermions. Our results reveal distinct differences between the cases of short-range and Coulomb randomly distributed scatterers. We speculate that this behavior is related to the Boltzmann transport theory prediction of dirty-limit behavior for Coulomb scatterers. © 2007 The American Physical Society URL:
