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…
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…
Modified MBE hardware and techniques and role of gallium purity for attainment of two dimensional electron gas mobility >35 x10^6 cm^2/Vs in AlGaAs/GaAs quantum wells grown by MBE
Geoffrey C. Gardner, Saeed Fallahi, John D. Watson +1
We provide evidence that gallium purity is the primary impediment to attainment of ultra-high mobility in a two-dimensional electron gas (2DEG) in AlGaAs/GaAs heterostructures grow…
Scattering Mechanisms in a High Mobility Low Density Carbon-Doped (100) GaAs Two-Dimensional Hole System
J. D. Watson, S. Mondal, G. A. Csáthy +5
We report on a systematic study of the density dependence of mobility in a low-density Carbon-doped (100) GaAs two-dimensional hole system (2DHS). At T= 50 mK, a mobility of 2.6 x…
