Quantum critical behaviour of the plateau-insulator transition in the quantum Hall regime
A. de Visser, L. A. Ponomarenko, G. Galistu +4
High-field magnetotransport experiments provide an excellent tool to investigate the plateau-insulator phase transition in the integral quantum Hall effect. Here we review recent l…
Observation of the quantized Hall insulator in the quantum critical regime of the two-dimensional electron gas
D. T. N. de Lang, L. A. Ponomarenko, A. de Visser +1
We have investigated the Hall resistance near the plateau-insulator transition of a two-dimensional electron gas in the quantum critical regime. High-field magnetotransport d…
The effects of macroscopic inhomogeneities on the magneto transport properties of the electron gas in two dimensions
B. Karmakar, M. R. Gokhale, A. P. Shah +5
In experiments on electron transport the macroscopic inhomogeneities in the sample play a fundamental role. In this paper and a subsequent one we introduce and develop a general fo…
New Insights into the Plateau-Insulator Transition in the Quantum Hall Regime
L. A. Ponomarenko, D. T. N. de Lang, A. de Visser +4
We have measured the quantum critical behavior of the plateau-insulator (PI) transition in a low-mobility InGaAs/GaAs quantum well. The longitudinal resistivity measured for two di…
The effect of carrier density gradients on magnetotransport data measured in Hall bar geometry
L. A. Ponomarenko, D. T. N. de Lang, A. de Visser +4
We have measured magnetotransport of the two-dimensional electron gas in a Hall bar geometry in the presence of small carrier density gradients. We find that the longitudinal resis…
Quantum criticality, particle-hole symmetry, and duality of the plateau-insulator transition in the quantum Hall regime
A. M. M. Pruisken, D. T. N. de Lang, L. A. Ponomarenko +1
We report new experimental data on the plateau-insulator transition in the quantum Hall regime, taken from a low mobility InGaAs/InP heterostructure. By employing the fundamental s…
