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…
Helicity sensitive terahertz radiation detection by dual-grating-gate high electron mobility transistors
P. Faltermeier, P. Olbrich, W. Probst +5
We report on the observation of a radiation helicity sensitive photocurrent excited by terahertz (THz) radiation in dual-grating-gate (DGG) InAlAs/InGaAs/InAlAs/InP high electron m…
Terahertz Radiation Detection by Field Effect Transistor in Magnetic Field
S. Boubanga-Tombet, M. Sakowicz, D. Coquillat +6
We report on terahertz radiation detection with InGaAs/InAlAs Field Effect Transistors in quantizing magnetic field. The photovoltaic detection signal is investigated at 4.2 K as a…
