Observation of reentrant quantum Hall states in the lowest Landau level
Yang Liu, C. G. Pappas, M. Shayegan +3
Measurements in very low disorder two-dimensional electrons confined to relatively wide GaAs quantum well samples with tunable density reveal reentrant integer quantum Hall s…
Imaging of the Coulomb driven quantum Hall edge states
Keji Lai, Worasom Kundhikanjana, Michael A. Kelly +3
The edges of a two-dimensional electron gas (2DEG) in the quantum Hall effect (QHE) regime are divided into alternating metallic and insulating strips, with their widths determined…
Reentrant nu = 1 quantum Hall state in a two-dimensional hole system
A. L. Graninger, D. Kamburov, M. Shayegan +4
We report the observation of a reentrant quantum Hall state at the Landau level filling factor nu = 1 in a two-dimensional hole system confined to a 35-nm-wide (001) GaAs quantum w…
Evolution of the 7/2 fractional quantum Hall state in two-subband systems
Yang Liu, J. Shabani, D. Kamburov +4
We report the evolution of the fractional quantum Hall state (FQHS) at even-denominator filling factor in wide GaAs quantum wells in which electrons occupy two electric sub…
Effective Mass and Spin Susceptibility of Dilute Two-Dimensional Holes in GaAs
YenTing Chiu, Medini Padmanabhan, T. Gokmen +4
We report effective hole mass () measurements through analyzing the temperature dependence of Shubnikov-de Haas oscillations in dilute (density cm$…
Anomalous robustness of the 5/2 fractional quantum Hall state near a sharp phase boundary
Yang Liu, D. Kamburov, M. Shayegan +3
We report magneto-transport measurements in wide GaAs quantum wells with tunable density to probe the stability of the fractional quantum Hall effect at filling factor 5/2 in…
