Cheianov, Vadim V. and Falko, Vladimir I. and Altshuler, Boris L. and Aleiner, Igor L. (2007) Random resistor network model of minimal conductivity in graphene. Physical Review Letters, 99 (17). p. 176801. ISSN 1079-7114Full text not available from this repository.
Transport in undoped graphene is related to percolating current patterns in the networks of n- and p-type regions reflecting the strong bipolar charge density fluctuations. Finite transparency of the p-n junctions is vital in establishing the macroscopic conductivity. We propose a random resistor network model to analyze scaling dependencies of the conductance on the doping and disorder, the quantum magnetoresistance and the corresponding dephasing rate.

|Additional Information:||We propose and solve a random resistor network model describing transport in graphene with inhomogeneous carrier density, where strong bipolar charge fluctuations form networks of n- and p-doped regions. Our theory explains numerous observations of minimal conductivity in graphene-based devices by experimentalists, e.g., at Manchester, Delft, Harvard, Maryland.
