Corbino-Enhanced Supersonic Acoustic-Emission Threshold in a GaAs Two-Dimensional Electron System
A. D. Levin, A. S. Jaroshevich, Z. D. Kvon +5
We report nonlinear differential-resistance measurements in a high-mobility GaAs/AlGaAs two-dimensional electron system patterned in a Corbino geometry. At zero magnetic field, $R_…

Hydrodynamic magnetotransport in a GaAs Corbino geometry
A. D. Levin, A. S. Jaroshevich, Z. D. Kvon +5
We report the observation of positive magnetoresistance in high-mobility GaAs Corbino devices. Over a broad intermediate-temperature range, the resistance exhibits a quadratic depe…
