Room Temperature Amplification of Terahertz Radiation by Grating-Gate Graphene Structures
Stephane Boubanga-Tombet, Wojciech Knap, Deepika Yadav +6
We report on experimental studies of terahertz (THz) radiation transmission through grating-gate graphene-channel transistor nanostructures and demonstrate room temperature THz rad…
Plasmonic instabilities and terahertz waves amplification in graphene metamaterials
Stephane Boubanga-Tombet, Deepika Yadav, Wojciech Knap +2
Plasmon oscillations have been intensively studied for more than forty years in conventional two-dimensional electron gas systems in order to find new alternatives to the vacuum de…
Noncentrosymmetric plasmon modes and giant terahertz photocurrent in a two-dimensional plasmonic crystal
V. V. Popov, D. V. Fateev, E. L. Ivchenko +1
We introduce and theoretically study the plasmon-photogalvanic effect in the planar noncentrosymmetric plasmonic crystal containing a homogeneous two-dimensional electron system ga…
Terahertz detection in a slit-grating-gate field-effect-transistor structure
D. M. Yermolayev, K. M. Maremyanin, D. V. Fateev +6
We have fabricated a grating-gate InGaAs/GaAs field-effect transistor structure with narrow slits between the grating gate fingers. The resonant photoconductive response of this st…
Giant terahertz near-field enhancement by two-dimensional plasmons
Arthur R. Davoyan, Vyacheslav V. Popov, Sergey A. Nikitov
We consider a periodically gated two-dimensional electron system, with a central gate finger biased independently creating a tunable plasmonic cavity in a planar plasmonic crystal.…
