Experimental Studies of Scaling Behavior of a Quantum Hall System with a Tunable Landau Level Mixing
Y. J. Zhao, T. Tu, X. J. Hao +3
Temperature dependence of the longitudinal and Hall resistance is studied in the regime of localization-delocalization transition. We carry out measurements of a scaling exponent $…
Observation of an in-plane magnetic-field-driven phase transition in a quantum Hall system with SU(4) symmetry
G. P. Guo, Y. J. Zhao, T. Tu +4
In condensed matter physics, the study of electronic states with SU(N) symmetry has attracted considerable and growing attention in recent years, as systems with such a symmetry ca…
Mechanism of Enhanced Rectification in Unimolecular Borromean Ring Devices
G. D. Scott, K. S. Chichak, A. J. Peters +3
We have studied charge transport through individual Borromean Ring complexes, both with and without anchor groups, in gated double barrier tunneling junctions (DBTJs) formed using…
Landau Level Anticrossing Manifestations in the Phase Diagram Topology of a Two Subband System
X. C. Zhang, I. Martin, H. W. Jiang
In a two-subband GaAs/AlGaAs two-dimensional electron system, the phase diagram of longitudinal resistivity ρ_xx in density and magnetic field plane exhibits an intriguing structur…
Nonequilibrium Magnetization of a Two-Dimensional Electron Gas in a Static Magnetic Field
D. R. Faulhaber, H. W. Jiang
Using a sensitive DC torque magnetometer we measure the orbital magnetization by sweeping the density at fixed magnetic fields on GaAs-AlGaAs heterostructures. At low temperatures…
Multiple Phases with the Same Quantized Hall Conductance in a Two-Subband System
X. C. Zhang, D. R. Faulhaber, H. W. Jiang
In a GaAs/AlGaAs two-dimensional electron system with two occupied subbands, the experimentally determined phase diagram in the density-magnetic field plane exhibits rich topologic…
