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: Density functional theory calculations indicate that boron dopants interact strongly with the underlying copper substrate while nitrogen dopants do not, and the distribution of dopants is observed to be completely random in the case of bor on, while nitrogen displays strong sublattice clustering.

TL;DR: It is found that creating well-defined contacts can suppress inelastic transport channels in graphene nanostructures and significantly influences the charge transport through the graphene nanoribbon but does not affect its electronic structure.

The rise of graphene
TL;DR: Owing to its unusual electronic spectrum, graphene has led to the emergence of a new paradigm of 'relativistic' condensed-matter physics, where quantum relativistic phenomena can now be mimicked and tested in table-top experiments.
