Insulator, semiclassical oscillations and quantum Hall liquids at low magnetic fields
Shun-Tsung Lo, Yi-Ting Wang, G Bohra +9
Magneto-transport measurements are performed on two-dimensional GaAs electron systems to probe the quantum Hall (QH) effect at low magnetic fields. Oscillations following the Shubn…
Probing temperature-driven flow lines in a gated two-dimensional electron gas with tunable spin-splitting
Yi-Ting Wang, Gil-Ho Kim, C. F. Huang +8
We study the temperature flow of conductivities in a gated GaAs two-dimensional electron gas (2DEG) containing self-assembled InAs dots and compare the results with recent theoreti…
Half integer features in the quantum Hall Effect: experiment and theory
Tobias Kramer, Eric J. Heller, Robert E. Parrott +6
The quantum Hall effect is one of the most important developments in condensed matter physics of the 20th century. The standard explanations of the famous integer quantized Hall pl…
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…
An experimental study on (2) modular symmetry in the quantum Hall system with a small spin-splitting
C. F. Huang, Y. H. Chang, H. H. Cheng +6
Magnetic-field-induced phase transitions were studied with a two-dimensional electron AlGaAs/GaAs system. The temperature-driven flow diagram shows the features of the (2) modul…
From semiclassical transport to quantum Hall effect under low-field Landau quantization
D. R. Hang, C. F. Huang, Y. W. Zhang +3
The crossover from the semiclassical transport to quantum Hall effect is studied by examining a two-dimensional electron system in an AlGaAs/GaAs heterostructure. By probing the ma…
