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

Electronic and transport properties of boron-doped graphene nanoribbons.
TL;DR: It is found that the electronic scattering process is spin-anisotropic; namely, the spin-down (up) transmittance channels are weakly (strongly) reduced by the presence of boron atoms, which can be controlled by the width of the nanoribbon.

Quantum transport of massless Dirac fermions.
TL;DR: A numerical study of the conductivity of disordered two-dimensional massless Dirac fermions reveals distinct differences between the cases of short-range and Coulomb randomly distributed scatterers, speculation that this behavior is related to the Boltzmann transport theory prediction of dirty-limit behavior for Coulomb scatterer.
