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

Quasiparticle Energies and Band Gaps of Graphene Nanoribbons
TL;DR: The quasiparticle band gaps found here suggest that use of GNRs for electronic device components in ambient conditions may be viable, and compared with previous tight-binding and density functional theory studies, show significant self-energy corrections.

TL;DR: Graphene weak-localization magnetoresistance is strongly suppressed and, in some cases, completely absent, due to mesoscopic corrugations of graphene sheets which can cause a dephasing effect similar to that of a random magnetic field.

TL;DR: Graphene multilayers are grown epitaxially on single crystal silicon carbide as discussed by the authors, which is composed of several graphene layers of which the first layer is electron doped due to the built-in electric field and the other layers are essentially undoped Unlike graphite the charge carriers show Dirac particle properties (i.e., an anomalous Berry's phase, weak anti-localization and square root field dependence of the Landau level energies).
