Quantum kinetic equation and universal conductance fluctuations in graphene
arXiv:0801.2394 · doi:10.1103/PhysRevB.77.193403
Abstract
We analyze universal conductance fluctuations (UCF) in graphene in the framework of diagrammatic perturbation theory in the metallic regime. It is shown that strong inter-valley scattering lifts the valley degeneracy of electronic states, whereas at weak inter-valley scattering two valleys contribute independently such that the variance of UCF would be expected to show sample- and geometry-dependent behavior.
