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…
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…
Interaction Induced Magnetotransport in a 2D Dirac-Heavy Hole Hybrid Band System
G. M. Gusev, A. D. Levin, V. A. Chitta +2
While electron-electron (e-e) interactions are known to influence resistivity in non-Galilean invariant two-dimensional (2D) systems, their effect on magnetotransport is not fully…
Magnetotransport in a 2D Hybrid Band System: Dirac and Heavy Hole Interplay
G. M. Gusev, A. D. Levin, V. A. Chitta +2
We investigate magnetoresistivity and the Hall effect in a 6.3 nm gapless HgTe quantum well - a two-dimensional hybrid band system featuring coexisting linear (Dirac-like) and para…
