Restricted access - publisher's policyWe show the first THz emission of a graphene based plasmonic antenna structure. Furthermore we present the minimum material requirements for an operational graphene antenna in terms of chemical potential µc and relaxation time t.
Material-dependencies of the THz emission from plasmonic graphene-based photoconductive antenna structures Suessmeier, Christoph; Abadal Cavallé, Sergi; Stock, Daniel; Schaeffer, Stephan; Alarcón Cot, Eduardo José; Hosseininejad, Seyed Ehsan; Wigger, Anna K.; Wagner, Stefan; Cabellos Aparicio, Alberto; Lemme, Max; Bolívar, Peter Haring (Institute of Electrical and Electronics Engineers (IEEE), 2017)
Restricted access - publisher's policyGraphene supports surface plasmon polaritons with comparatively slow propagation velocities in the THz region, which becomes increasingly interesting for future communication technologies. This ability can be used to realize ...
