Probing semiclassical magneto-oscillations in the low-field quantum Hall effect
D. R. Hang, C. F. Huang, K. A. Cheng
The low-field quantum Hall effect is investigated on a two-dimensional electron system in an AlGaAs/GaAs heterostructure. Magneto-oscillations following the semiclassical Shubnikov…
Probing Landau quantisation with the presence of insulator-quantum Hall transition in a GaAs two-dimensional electron system
Kuang Yao Chen, Y. H. Chang, C. -T. Liang +9
Magneto-transport measurements are performed on the two-dimensional electron system (2DES) in an AlGaAs/GaAs heterostructure. By increasing the magnetic field perpendicular to the…
Quantum Beating in Ring Conductance: Observation of Spin Chiral States and Berry's phase
M. J. Yang, C. H. Yang, K. A. Cheng +1
Using singly connected rings with a collimating contact to current leads, we have observed the spin quantum beating in the Aharonov-Bohm conductance oscillations. We demonstrate th…
Characterization of one-dimensional quantum channels in InAs/AlSb
C. H. Yang, M. J. Yang, K. A. Cheng +1
We report the magnetoresistance characteristics of one-dimensional electrons confined in a single InAs quantum well sandwiched between AlSb barriers. As a result of a novel nanofab…
