Abstract
This article reviews the basic theoretical aspects of graphene, a one-atom-thick allotrope of carbon, with unusual two-dimensional Dirac-like electronic excitations. The Dirac electrons can be controlled by application of external electric and magnetic fields, or by altering sample geometry and/or topology. The Dirac electrons behave in unusual ways in tunneling, confinement, and the integer quantum Hall effect. The electronic properties of graphene stacks are discussed and vary with stacking order and number of layers. Edge (surface) states in graphene depend on the edge termination (zigzag or armchair) and affect the physical properties of nanoribbons. Different types of disorder modify the Dirac equation leading to unusual spectroscopic and transport properties. The effects of electron-electron and electron-phonon interactions in single layer and multilayer graphene are also presented.

Quantum-Hall activation gaps in graphene.

TL;DR: The gap measured at nu=2 is strongly temperature and field dependent and approaches the expected value for sharp Landau levels for fields B>20 T and temperatures T>100 K, explaining this surprising behavior by a narrowing of the lowest Landau level.

Numerical studies of conductivity and Fano factor in disordered graphene

TL;DR: In this article, the problem of electron transport in a disordered single-layer graphene sheet was studied using the recursive Green's function method, and it was shown that the conductivity is of order (e}^{2}∕h$ and its dependence on the carrier density has a scaling form controlled solely by the disorder strength and the ratio between the sample size and the correlation length of the disorder potential.
