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 structure of chiral graphene tubules
TL;DR: In this paper, the electronic structure for graphenemonolayer tubules is predicted as a function of the diameter and helicity of the constituent graphene tubules, and it is shown that approximately 1/3 of these tubules are a one-dimensional metal which is stable against a Peierls distortion, and the other 2/3 are onedimensional semiconductors.

TL;DR: It is shown that when graphene is epitaxially grown on SiC substrate, a gap of approximately 0.26 eV is produced and it is proposed that the origin of this gap is the breaking of sublattice symmetry owing to the graphene-substrate interaction.
