Numerical study of electronic transport through bilayer graphene nanoribbons

In graphene, a sheet of carbon atoms arranged in a honeycomb structure, charge carriers behave as massless Dirac fermions and move with extremely high speed leading to exotic electronic properties. However, lack of a band-gap reduces its utility for conventional electronic device applications. A tunable bandgap can be induced in bilayer graphene by application of a potential difference between the two layers.
