Singularity-enhanced terahertz detection in high-mobility field-effect transistors
Michail Khavronin, Aleksandr S. Petrov, Aleksandr E. Kazantsev +2
Detectors of high-frequency radiation based on high-electron-mobility transistors benefit from low noise, room-temperature operation, and the possibility to perform radiation spect…
Thresholdless excitation of edge plasmons by transverse current
Aleksandr S. Petrov, Dmitry Svintsov
We theoretically demonstrate that dc electron flow across the junction of two-dimensional electron systems leads to excitation of edge magnetoplasmons. The threshold current for su…
Perturbation theory for two-dimensional hydrodynamic plasmons
Aleksandr S. Petrov, Dmitry Svintsov
Perturbation theory is an indispensable tool in quantum mechanics and electrodynamics that handles weak effects on particle motion or fields. However, its extension to plasmons inv…
Asymmetry-driven plasmon instabilities in confined hydrodynamic electron flows
Aleksandr S. Petrov, Dmitry Svintsov
Direct current in confined two-dimensional (2d) electron systems can become unstable with respect to the excitation of plasmons. Numerous experiments and simulations hint that stru…
