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…
Measurements of Composite Fermion Conductivity Dependence on Carrier Density
C. -T. Liang, M. Y. Simmons, D. A. Ritchie +1
We present the first experimental study of the carrier density dependence of the composite fermion conductivity at Landau level filling factors and $ν= {3/…
Can the conductance of an adiabatic ballistic constriction be lower than ?
C. -T. Liang, O. A. Tkachenko, V. A. Tkachenko +4
We have performed four-terminal conductance measurements of a one-dimensional (1D) channel in which it is possible to modulate the potential profile using three overlaying finger g…
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…
