Abstract: Current-voltage and current-field characteristics for graphene with Anderson interaction of conduction and impurity electrons are calculated by the “average electron” method in the case of low temperatures. These characteristics are analyzed depending on the frequency of an external ac electric field and a magnetic field. A portion with absolute negative conductivity is detected.
