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

TL;DR: Stimulated by recent advances in isolating graphene and similarities to single-wall carbon nanotubes, simulations were performed to assess the effects of static disorder on the conductance of metallic armchair- and zigzag-edge graphene nanostrips, found to have outstanding ballistic transport properties in the presence of a substrate-induced disorder.

TL;DR: In infrared studies of the Landau level (LL) transitions in single layer graphene, the lack of precise scaling between different LL transitions indicates considerable contributions of many-particle effects to the infrared transition energies.

Nonadiabatic kohn anomaly in a doped graphene monolayer
Michele Lazzeri,Francesco Mauri +1 more
TL;DR: Graphene is a spectacular example where the adiabatic Born-Oppenheimer approximation miserably fails and the frequency weakly depends on the doping, while the dynamic one rapidly varies because of a Kohn anomaly.
