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…
Biased bilayer graphene: semiconductor with a gap tunable by the electric field effect.
- E. Castro, K. Novoselov, A. Neto

- 13 November 2006
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.
Electronic properties of disordered two-dimensional carbon
Two-dimensional carbon, or graphene, is a semimetal that presents unusual low-energy electronic excitations described in terms of Dirac fermions. We analyze in a self-consistent way the effects of…
