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…
Effects of Zeeman spin splitting on the modular symmetry in the quantum Hall effect
D. R. Hang, R. B. Dunford, Gil-Ho Kim +7
Magnetic-field-induced phase transitions in the integer quantum Hall effect are studied under the formation of paired Landau bands arising from Zeeman spin splitting. By investigat…
Studies of the Temperature-Driven Flow Lines and Phase Transitions in a Two-Dimensional Si/SiGe Hole System
C. T. Liang, C. F. Huang, Yu-Ming Cheng +3
We have performed low-temperature transport experiments on a Si/SiGe hole system. The measured transverse and longitudinal condductivities and allow us to study t…
