Anisotropic conductivity of doped graphene due to short-range nonsymmetric scattering

The conductivity of doped graphene is considered taking into account scattering by short-range nonsymmetrical defects, when the longitudinal and transverse components of conductivity tensor appear to be different. The calculations of the anisotropic conductivity tensor are based on the quasiclassical kinetic equation for the case of monopolar transport at low temperatures. The effective longitudinal conductivity and the transverse voltage, which are controlled by orientation of sample and by gate voltage (i.e., doping level), are presented.
