The electronic properties of graphene
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… Expand
Substrate-induced bandgap opening in epitaxial graphene.
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. Expand
Energy gaps and a zero-field quantum Hall effect in graphene by strain engineering
Owing to the fact that graphene is just one atom thick, it has been suggested that it might be possible to control its properties by subjecting it to mechanical strain. New analysis indicates not… Expand
Gauge fields in graphene
The physics of graphene is acting as a bridge between quantum field theory and condensed matter physics due to the special quality of the graphene quasiparticles behaving as massless two dimensional… Expand
Science and technology roadmap for graphene, related two-dimensional crystals, and hybrid systems.
An overview of the key aspects of graphene and related materials, ranging from fundamental research challenges to a variety of applications in a large number of sectors, highlighting the steps necessary to take GRMs from a state of raw potential to a point where they might revolutionize multiple industries are provided.

Dynamical polarization of graphene at finite doping
The polarization of graphene is calculated exactly within the random phase approximation for arbitrary frequency, wavevector and doping. At finite doping, the static susceptibility saturates to a… Expand
Electron-Electron Interactions in Graphene: Current Status and Perspectives
We review the problem of electron-electron interactions in graphene. Starting from the screening of long range interactions in these systems, we discuss the existence of an emerging Dirac liquid of… Expand
Non-Fermi liquid behavior of electrons in the half-filled honeycomb lattice (A renormalization group approach)
A system of electrons in the two-dimensional honeycomb lattice with Coulomb interactions is described by a renormalizable quantum field theory similar but not equal to QED3. Renormalization group… Expand

It is demonstrated that the electronic gap of a graphene bilayer can be controlled externally by applying a gate bias and can be changed from zero to midinfrared energies by using fields of less, approximately < 1 V/nm, below the electric breakdown of SiO2. Expand
Strain-Induced Pseudo–Magnetic Fields Greater Than 300 Tesla in Graphene Nanobubbles
Straining Graphene's Electronic States The conduction electrons in graphene, single sheets of graphite, can have very high mobilities. Under the influence of an applied magnetic field, a series of… Expand
