摘要

在石墨烯中,一层碳原子呈蜂窝状排列,载流子表现为无质量的狄拉克费米子,并以极高的速度移动,从而产生奇异的电子特性。然而,缺乏带隙降低了其在传统电子器件应用中的效用。利用两层之间的电位差,可以在双层石墨烯中诱导出可调谐的带隙。

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.
