A roadmap for graphene
TLDR
This work reviews recent progress in graphene research and in the development of production methods, and critically analyse the feasibility of various graphene applications. Expand
Landau-level degeneracy and quantum Hall effect in a graphite bilayer.
We derive an effective two-dimensional Hamiltonian to describe the low-energy electronic excitations of a graphite bilayer, which correspond to chiral quasiparticles with a parabolic dispersion… Expand
Science and technology roadmap for graphene, related two-dimensional crystals, and hybrid systems.
TLDR
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. Expand
Unconventional quantum Hall effect and Berry’s phase of 2π in bilayer graphene
There are two known distinct types of the integer quantum Hall effect. One is the conventional quantum Hall effect, characteristic of two-dimensional semiconductor systems1,2, and the other is its… Expand
Selective transmission of Dirac electrons and ballistic magnetoresistance of n − p junctions in graphene
We show that an electrostatically created n-p junction separating the electron and hole gas regions in a graphene monolayer transmits only those quasiparticles that approach it almost perpendicularly… Expand
k·p theory for two-dimensional transition metal dichalcogenide semiconductors
We present k.p Hamiltonians parametrized by ab initio density functional theory calculations to describe the dispersion of the valence and conduction bands at their extrema (the K , Q , Γ , and M… Expand
Weak-localization magnetoresistance and valley symmetry in graphene.
TLDR
This work evaluates the dependence of the magnetoresistance of graphene on relaxation rates associated with various possible ways of breaking a "hidden" valley symmetry of the system by evaluating the dependent rates of trigonal warping and intervalley scattering. Expand
The Focusing of Electron Flow and a Veselago Lens in Graphene p-n Junctions
TLDR
The focusing of electric current by a single p-n junction in graphene is theoretically predicted and may be useful for the engineering of electronic lenses and focused beam splitters using gate-controlled n-p-n junctions in graphene-based transistors. Expand
Cloning of Dirac fermions in graphene superlattices
TLDR
Graphene superlattices such as this one provide a way of studying the rich physics expected in incommensurable quantum systems and illustrate the possibility of controllably modifying the electronic spectra of two-dimensional atomic crystals by varying their crystallographic alignment within van der Waals heterostuctures. Expand
Electrically tunable band gap in silicene
We report calculations of the electronic structure of silicene and the stability of its weakly buckled honeycomb lattice in an external electric field oriented perpendicular to the monolayer of Si… Expand
