Graphene has attracted enormous research interest because of its extraordinary electronic and optical properties.It is a single atomic-layer,and two-dimensional structure with honeycomb crystal lattices.Graphene is a zero band-gap semiconductor,thus giving rise to unique electronic properties such asa high Fermi velocity (~1/300 of the speed of light),a vanishing effective mass,a huge electrical mobility,and so on.
