Hidden Quantum Hall Stripes in AlGaAs/AlGaAs Quantum Wells
X. Fu, Yi Huang, Q. Shi +4
We report on transport signatures of hidden quantum Hall stripe (hQHS) phases in high () half-filled Landau levels of AlGaAs/AlGaAs quantum w…
Nonlinear transport in 2D electron gas exhibiting colossal negative magnetoresistance
Q. Shi, M. A. Zudov, L. N. Pfeiffer +1
We report on nonlinear transport measurements in a GaAs/AlGaAs quantum well exhibiting a colossal negative magnetoresistance effect. Under applied dc bias, the magnetoresistance be…
Hall field-induced resistance oscillations in Ge/SiGe quantum wells
Q. Shi, M. A. Zudov, O. A. Mironov +1
We report on a magnetotransport study in a high-mobility 2D hole gas hosted in a pure Ge/SiGe quantum well subject to dc electric fields and high frequency microwave radiation. We…
Colossal negative magnetoresistance in a 2D electron gas
Q. Shi, P. D. Martin, Q. A. Ebner +3
We report on a colossal negative magnetoresistance (MR) in GaAs/AlGaAs quantum well which, at low temperatures, is manifested by a drop of the resistivity by more than an order of…
Observation of microwave-induced resistance oscillations in strained Ge/SiGe quantum wells
M. A. Zudov, O. A. Mironov, Q. A. Ebner +3
Microwave-induced resistance oscillations (MIRO) have been extensively studied for more than a decade but, until now, have remained unique to GaAs/AlGaAs-based 2D electron systems.…
