Energy-loss rate of a fast particle in graphene

Abstract


  • The energy-loss rate of a fast particle in graphene is studied. The energy-loss rate always increases

    with increasing incident particle energy, which is quite unusual when compared to electron gas in

    normal metal. Graphene exhibits a “discriminating” behavior where there exists a low energy cutoff

    below which the scattering process is strictly forbidden, leading to lossless traverse of an

    external particle in graphene. This low energy cutoff is of the order of nearest neighbor hopping

    bandwidth. Our results suggest that backscattering is also absent in the external particle scattering

    of graphene.
