      We 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.

    • Analysis of a plasmonic graphene antenna for microelectronic applications 

      Suessrneier, C.; Thiel, F.; Wigger, Anna K.; Bolívar, Peter Haring; Abadal Cavallé, Sergi; Alarcón Cot, Eduardo José; Cabcllos Aparicio, A.; Banszcrus, L.; Stampfer, C.; Lemme, M. (Institute of Electrical and Electronics Engineers (IEEE), 2018)

      Graphene offers a large potential to downscale antennas to the micrometer scale, due to its special dispersion relation and its ability to support plasmons in the THz frequency range. For an adequate performance of the ...

    • 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)
