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 …

Monolayer graphene exhibits extraordinary properties owing to the unique, regular
arrangement of atoms in it. However, graphene is usually modified for specific applications …

The electronic bandgap is an intrinsic property of semiconductors and insulators that largely
determines their transport and optical properties. As such, it has a central role in modern …

The optical conductance of monolayer graphene is defined solely by the fine structure
constant, α= e^2/ℏc (where e is the electron charge, ℏ is Dirac's constant and c is the speed …

Graphene, a single monolayer of graphite, has recently attracted considerable interest
owing to its novel magneto-transport properties,,, high carrier mobility and ballistic transport …

Carbon is one of the most intriguing elements in the Periodic Table. It forms many allotropes,
some known from ancient times (diamond and graphite) and some discovered 10-20 years …

After the first unequivocal demonstration of spin transport in graphene [Tombros et al.,
Nature (London) 448, 571–574 (2007)], surprisingly at room temperature, it was quickly …

We review the electronic properties of bilayer graphene, beginning with a description of the
tight-binding model of bilayer graphene and the derivation of the effective Hamiltonian …

We demonstrate that the electronic gap of a graphene bilayer can be controlled externally by
applying a gate bias. From the magnetotransport data (Shubnikov–de Haas measurements …

We consider a graphene bilayer with a relative small angle rotation between the layers—a
stacking defect often seen in the surface of graphite—and calculate the electronic structure …
