  • Title: Tunable Terahertz Hybrid Metal-Graphene Plasmons.
    Author: Jadidi MM, Sushkov AB, Myers-Ward RL, Boyd AK, Daniels KM, Gaskill DK, Fuhrer MS, Drew HD, Murphy TE.
    Journal: Nano Lett; 2015 Oct 14; 15(10):7099-104. PubMed ID: 26397718.
    Abstract:
    We report here a new type of plasmon resonance that occurs when graphene is connected to a metal. These new plasmon modes offer the potential to incorporate a tunable plasmonic channel into a device with electrical contacts, a critical step toward practical graphene terahertz optoelectronics. Through theory and experiments, we demonstrate, for example, anomalously high resonant absorption or transmission when subwavelength graphene-filled apertures are introduced into an otherwise conductive layer. These tunable plasmon resonances are essential yet missing ingredients needed for terahertz filters, oscillators, detectors, and modulators.
