Discrete states and ballistic interference in quantum wires approaching macroscopic lengths
Henok Weldeyesus, Taras Patlatiuk, Christian P. Scheller +4
Increasing the size of a system showing quantum effects is a difficult task limited by decoherence, a diminishing quantum level spacing, and the effects of disorder spoiling the qu…
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 .…
Density Dependence of the Phases of the Integer Quantum Hall Plateau in Low Disorder Electron Gases
Haoyun Huang, Waseem Hussain, S. A. Myers +3
Recent magnetotransport measurements in low-disorder electron systems confined to GaAs/AlGaAs samples revealed that the integer quantum Hall plateau is broken into three di…
Total Faraday rotation by the Hall effect in a 2D electron gas
Vishnunarayanan Suresh, Talia J. Martz-Oberlander, Sujatha Vijayakrishnan +5
We report the realization of near total Faraday rotation of =1.43 rad (82 degrees) on a single pass through a 2D electron gas (2DEG), approaching the ideal limit of ra…
Collective neutral excitations as sensitive probe for the quality of 2D charge carrier systems in ultra-pure GaAs quantum wells
Ursula Wurstbauer, Michael J. Manfra, Ken W. West +1
Ultra-clean low-dimensional interacting charge carrier systems are the basis to explore correlated states and phases. We report the observation of very narrow collective intersubba…
