Stability of multielectron bubbles in high Landau levels
Dohyung Ro, S. A. Myers, N. Deng +5
We study multielectron bubble phases in the and Landau levels in a high mobility GaAs/AlGaAs sample. We found that the longitudinal magnetoresistance versus temperature…
Disorder broadening of even denominator fractional quantum Hall states in the presence of a short-range alloy potential
E. Kleinbaum, Hongxi Li, N. Deng +3
We study energy gaps of the and fractional quantum Hall states in a series of two-dimensional electron gases containing alloy disorder. We found that gaps at these…
Electron Bubbles and the Structure of the Orbital Wavefunction
Dohyung Ro, N. Deng, J. D. Watson +4
Stripe-like and bubble-like patterns spontaneously form in numerous physical, chemical, and biological systems when competing long-range and short-range interactions banish uniform…
The Fractional Quantum Hall State in the Presence of Alloy Disorder
Nianpei Deng, G. C. Gardner, S. Mondal +3
We report quantitative measurements of the impact of alloy disorder on the fractional quantum Hall state. Alloy disorder is controlled by the aluminum content in the Al…
Growth and electrical characterization of Al0.24Ga0.76As/AlxGa1-xAs/Al0.24Ga0.76As modulation-doped quantum wells with extremely low x
Geoffrey C. Gardner, John D. Watson, Sumit Mondal +3
We report on the growth and electrical characterization of modulation-doped Al0.24Ga0.76As/AlxGa1-xAs/Al0.24Ga0.76As quantum wells with mole fractions as low as x=0.00057. Such str…
Contrasting Energy Scales of the Reentrant Integer Quantum Hall States
N. Deng, J. D. Watson, L. P. Rokhinson +2
We report drastically different onset temperatures of the reentrant integer quantum Hall states in the second and third Landau level. This finding is in quantitative disagreement w…
