Bias-induced breakdown of electron solids in the second Landau level
Alexander V. Rossokhaty, Silvia Lüscher, Joshua A. Folk +3
Reentrant integer quantum Hall (RIQH) states are believed to be correlated electron solid phases, though their microscopic description remains unclear. As bias current increases, l…
Low-temperature illumination and annealing of ultra-high quality quantum wells
Mohammad Samani, Alexander V. Rossokhaty, Ebrahim Sajadi +5
The effects of low temperature illumination and annealing on fractional quantum Hall (FQH) characteristics of a GaAs/AlGaAs quantum well are investigated. Illumination alone, below…
Field-effect-induced two-dimensional electron gas utilizing modulation doping for improved ohmic contacts
Sumit Mondal, Geoffrey C. Gardner, John D. Watson +3
Modulation-doped AlGaAs/GaAs heterostructures are utilized extensively in the study of quantum transport in nanostructures, but charge fluctuations associated with remote ionized d…
Superradiant Decay of Cyclotron Resonance of Two-Dimensional Electron Gases
Qi Zhang, Takashi Arikawa, Eiji Kato +9
We report on the observation of collective radiative decay, or superradiance, of cyclotron resonance (CR) in high-mobility two-dimensional electron gases in GaAs quantum wells usin…
