摘要: A system of generalized kinetic equations for the distribution functions two-dimensional Dirac fermions scattered by impurities is derived in Born approximation with respect to short-range impurity potential. It proven that conductivity following from classical Boltzmann equation picture, where electrons or holes have scattering amplitude reduced due chirality, justified except an exponentially narrow range chemical potential near conical point. When this range, creation infinite number electron-hole pairs related quasi-relativistic nature graphene results a renormalization minimal as compared term and logarithmic corrections similar Kondo effect.
