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…
From insulator to quantum Hall liquid at low magnetic fields
Tsai-Yu Huang, C. -T. Liang, Gil-Ho Kim +5
We have performed low-temperature transport measurements on a GaAs two-dimensional electron system at low magnetic fields. Multiple temperature-independent points and accompanying…
On the low-field insulator-quantum Hall conductor transitions
Tsai-Yu Huang, J. R. Juang, C. F. Huang +7
We studied the insulator-quantum Hall conductor transition which separates the low-field insulator from the quantum Hall state of the filling factor on a gated two-dimensiona…
A study on the universality of the magnetic-field-induced phase transitions in the two-dimensional electron system in an AlGaAs/GaAs heterostructure
C. F. Huang, Y. H. Chang, H. H. Cheng +2
Plateau-plateau (P-P) and insulator-quantum Hall conductor (I-QH) transitions are observed in the two-dimensional electron system in an AlGaAs/GaAs heterostructure. At high fields,…
Detection of Coulomb Charging around an Antidot
M. Kataoka, C. J. B. Ford, G. Faini +5
We have detected oscillations of the charge around a potential hill (antidot) in a two-dimensional electron gas as a function of a perpendicular magnetic field B. The field confine…
Detection of Coulomb Charging around an Antidot in the Quantum Hall Regime
M. Kataoka, C. J. B. Ford, G. Faini +5
We have detected oscillations of the charge around a potential hill (antidot) in a two-dimensional electron gas as a function of a large magnetic field B. The field confines electr…
Spin-dependent transport in a clean one-dimensional channel
C. -T. Liang, M. Y. Simmons, C. G. Smith +3
A shoulder-like feature close to , "the 0.7 structure" at zero magnetic field was observed in clean one-dimensional (1D) channels [K.J. Thomas et al., Phys. R…
Experimental evidence of a metal-insulator transition in a half-filled Landau level
C. -T. Liang, J. E. F. Frost, M. Y. Simmons +2
We have measured the low-temperature transport properties of a high-mobility front-gated GaAs/Al_{0.33}Ga_{0.67}As heterostructure. By changing the applied gate voltage, we can var…
