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…
Comparison of reverse current mechanisms in GaN Schottky diodes grown on sapphire versus ammonothermal GaN substrates
B. Orfao, M. Abou Daher, H. Bouillaud +5
In this work, we analyse the reverse current mechanisms in GaN Schottky barrier diodes (SBDs) grown on sapphire and native GaN substrates. For the sapphire-substrate sample, two co…
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…
