Potential of Graphene/AlGaN/GaN heterostructures to study the drag and two-stream instability effects
A. Rehman, D. B. But, P. Sai +6
Graphene/AlGaN/GaN heterostructures are proposed to investigate the drag and two-stream instability effects. In this study, graphene grown by chemical vapor deposition was transfer…
Effect of current on terahertz plasmons in AlGaN/GaN heterostructures
M. Dub, P. Sai, Y. Ivonyak +3
Terahertz transmittance spectra of plasmonic crystals based on two-dimensional electron gas in AlGaN/GaN heterostructures were studied in grating-gate and gateless plasmonic crysta…
Effect of temperature on 2D terahertz plasmons and electron effective mass in AlGaN/GaN
M. Dub, P. Sai, D. Yavorskiy +6
The effect of temperature on two-dimensional plasmons in large-area AlGaN/GaN plasmonic crystals was studied experimentally. With the temperature increase the resonant plasmon freq…
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…
