Extreme Terahertz Nonlinearity of AlGaN/GaN-based Grating-Gate Plasmonic Crystals
Pavlo Sai, Vadym V. Korotyeyev, Dmytro B. But +12
We present a novel approach to enhance THz nonlinearity by the resonant excitation of two-dimensional plasmons in grating-gate plasmonic crystals. Using a high-electric-field THz p…

Beatings of ratchet current magneto-oscillations in GaN-based grating gate structures: manifestation of spin-orbit band splitting
P. Sai, S. O. Potashin, M. Szola +8
We report on the study of the magnetic ratchet effect in AlGaN/GaN heterostructures superimposed with lateral superlattice formed by dual-grating gate structure. We demonstrate tha…

Field Effect Transistors for Terahertz Detection: Physics and First Imaging Applications
W. Knap, M. Dyakonov, D. Coquillat +11
Resonant frequencies of the two-dimensional plasma in FETs increase with the reduction of the channel dimensions and can reach the THz range for sub-micron gate lengths. Nonlinear…
