▎ 摘  要

We study two-dimensional transport of quasirelativistic electronic excitations in graphene in the presence of Coulomb impurities and topological structural defects described by static long-range-correlated random scalar and vector potentials, respectively. Our results for the transport and cyclotron rates as well as the decay rate of the Friedel oscillations provide the means of identifying the dominant scattering mechanism in graphene. We also discuss the properties of zero-energy states and pertinent localization scenarios.
