Possible nematic to smectic phase transition in a two-dimensional electron gas at half-filling
Q. Qian, J. Nakamura, S. Fallahi +2
Liquid crystalline phases of matter permeate nature and technology, with examples ranging from cell membranes to liquid-crystal displays. Remarkably, electronic liquid crystal phas…
Impact of silicon doping on low frequency charge noise and conductance drift in GaAs/AlGaAs nanostructures
S. Fallahi, J. R. Nakamura, G. C. Gardner +2
We present measurements of low frequency charge noise and conductance drift in modulation doped GaAs/AlGaAs heterostructures grown by molecular beam epitaxy in which the silicon do…
Optimization of edge state velocity in the integer quantum Hall regime
Harshad Sahasrabudhe, Bozidar Novakovic, James Nakamura +5
Observation of interference in the quantum Hall regime may be hampered by a small edge state velocity due to finite phase coherence time. Therefore designing two quantum point cont…
Quantum Lifetime in Ultra-High Quality GaAs Quantum Wells: Relationship to and Impact of Density Fluctuations
Qi Qian, James R. Nakamura, Saeed Fallahi +6
We consider quantum lifetime derived from low-field Shubnikov-de Haas oscillations as a metric of quality of the two-dimensional electron gas in GaAs quantum wells that expresses l…
High temperature resistivity measured at ν = 5/2 as a predictor of 2DEG quality in the N=1 Landau level
Qi Qian, James R. Nakamura, Saeed Fallahi +3
We report a high temperature (T = 0.3K) indicator of the excitation gap at the filling factor fractional quantum Hall state in ultra-high quality AlGaAs/GaAs two…
