Radiowave-induced Resistance Oscillations
E. Bell, C. Hnatovsky, K. W. Baldwin +4
Microwave-induced resistance oscillations (MIROs) \cite{zudov:2001a} occur when a 2D electron gas is subjected to radiation of frequency and varying magnetic field .…
Resonant Magneto-phonon Emission by Supersonic Electrons in Ultra-high Mobility Two-dimensional System
Z. T. Wang, M. Hilke, N. Fong +4
We investigate resonant acoustic phonon scattering in the magneto-resistivity of an ultra-high mobility two-dimensional electron gas system subject to DC current in the temperature…
High-order two-component fractional quantum Hall states around filling factor
E. Bell, K. W. Baldwin, L. N. Pfeiffer +2
Two-component fractional quantum Hall (2C-FQH) states in electron bilayers have been known for decades, yet their experimental realization remained limited to low-order fractions.…
Interaction-Driven Asymmetry in the Breakdown of the = 1 Quantum Hall State
Hoai Anh Ho, Jian Huang, L. N. Pfeiffer +1
We report real-time detection of longitudinal and transverse transport responses across distinct frequency bands in a ferromagnetic filling factor = 1 integer quantum Hall sta…
