"Quantum transport phenomana in graphene"
Graphene is a two-dimensional carbon material with a honeycomb lattice structure and Dirac-like low energy excitations. Motivated by recent graphene transport experiments, we have undertaken a numerical study of the conductivity of disordered two-dimensional massless Dirac fermions. We discuss the scattering mechanism in graphene samples, study quantum interference effect of Dirac fermions, in the absence and presence of a perpendicular magnetic field.
