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…
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…
Current-induced Magnetoexcitons in Mesoscopic Electron-hole Plasma
Yu. A. Pusep, M. A. T. Patricio, G. M. Jacobsen +3
A radical restructuring of the optical response of highly excited electron-hole plasma formed in a mesoscopic GaAs/AlGaAs channel in a quantizing magnetic field when an electric cu…
Bulk and shear viscosities in multicomponent 2D electron system
A. D. Levin, G. M. Gusev, V. A. Chitta +2
We investigated magnetotransport in mesoscopic samples containing electrons from three different subbands in GaAs triple wells. At high temperatures, we observed positive magnetore…
