Abstract


  • We demonstrate that the optical response of graphene nanoribbons in the terahertz to far-infrared

    regime can be significantly enhanced and tuned by an applied magnetic field. The dependence of the

    threshold frequency on the magnetic field is studied. The ribbons with the strongest terahertz

    conductance under a magnetic field are those with one-dimensional massless Dirac Fermion energy

    dispersion. For a given ribbon, there exists an optimal field under which the conductance resonance

    can occur at the lowest frequency.
