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.read more

Interplay between lattice-scale physics and the quantum Hall effect in graphene
TL;DR: In this paper, the authors focus on clean graphene sheets in the regime of quantum Hall ferromagnetism, and discuss how subtler lattice-scale physics, arising either from interactions or disorder, resolves this ambiguity to measurable consequence.

Quantum Theory of Transport in Narrow Channels
TL;DR: In this article, the conductivity of a semiconductor surface channel or a thin film is evaluated using a Green's-function formulation of perturbation theory, where boundary conditions at the surfaces of the channel are expressed in terms of a fluctuation potential rather than a Fuchs reflectivity parameter.

Electronic compressibility of a graphene bilayer.
TL;DR: In this article, the electronic compressibility arising from electron-electron interactions for a graphene bilayer within the Hartree-Fock approximation was calculated, and it was shown that due to the chiral nature of the particles in this system, the compressibility is rather different from those of either the two-dimensional electron gas or ordinary semiconductors.

TL;DR: In this article, the magnetic properties of a hypothetical rhomboedral graphite were determined and the thermal variation of the susceptibility was well represented by the relation: X = 0.85 + K 0 3 (1−e −ToT) and the experimental value of K0 is in good agreement with the theoretical value proposed by McClure.
