Electron Hydrodynamics and Bernoulli Effect in Venturi-Shaped 2D Systems
C. A. Monari, A. D. Levin, A. S. Jaroshevich +5
The study of electron hydrodynamics provides a powerful framework for understanding transport in ultraclean conductors, yet experimental evidence has thus far been largely restrict…
Magnetophonon Resistance Oscillations in Structures with a GaAs Quantum Well and Barriers of AlAs/GaAs-Si Superlattices
I. L. Drichko, I. Yu. Smirnov, M. O. Safonchik +3
Magnetophonon resistance oscillations (MPR) associated with the resonant scattering of electrons by optical phonons at temperatures of 77-240 K, as well as resonant scattering of e…
Effect of electric current on optical response of viscous electron-hole plasma
Yu. A. Pusep, M. A. T. Patricio, G. M. Jacobsen +3
The influence of the Hall voltage on the photoluminescence of a dense hydrodynamic electron-hole plasma laser generated in a mesoscopic n-doped GaAs channel under intense laser exc…
Electron Tesla valve
Daniil I. Sarypov, Dmitriy A. Pokhabov, Arthur G. Pogosov +3
In solids, frequent electron-electron collisions can induce collective, fluid-like electron transport. While this regime offers a powerful framework for exploring many-body phenome…
Spectroscopy of Heat Transport and Violation of the Wiedemann--Franz Law in a GaAs Hydrodynamic Mesoscopic Channel
Yu. A. Pusep, M. A. T. Patricio, M. M. Glazov +5
The Wiedemann--Franz law, which determines the universality of the ratio of thermal conductivity to electrical conductivity, is studied in the hydrodynamic electron transport regim…
Viscous Electron Flow and Nonlinear Magnetotransport in 2D Channels
A. D. Levin, G. M. Gusev, A. K. Bakarov
We examine nonlinear transport in a viscous two-dimensional electron fluid within narrow GaAs channels. The differential magnetoresistance shows nonmonotonic behavior, a signature…
