Impact of spin-orbit coupling on quantum Hall nematic phases
M. J. Manfra, R. de Picciotto, Z. Jiang +4
Anisotropic charge transport is observed in a two-dimensional (2D) hole system in a perpendicular magnetic field at filling factors nu=7/2, nu=11/2, and nu=13/2 at low temperature.…
Mesoscopic structures and 2D hole systems in fully field effect controlled heterostructures
R. L. Willett, M. J. Manfra, L. N. Pfeiffer +1
Two fundamental extensions to the function of previously described fully field effect two-dimensional (2D) electron heterostructures are presented: First, using the same basic hete…
Confinement of fractional quantum Hall states in narrow conducting channels
R. L. Willett, M. J. Manfra, L. N. Pfeiffer +1
Confinement of small-gapped fractional quantum Hall states facilitates quasiparticle manipulation and is an important step towards quasiparticle interference measurements. Demonstr…
Density and well width dependences of the effective mass of twodimensional holes in (100) GaAs quantum wells measured by cyclotron resonance at microwave frequencies
H. Zhu, K. Lai, D. C. Tsui +5
Cyclotron resonance at microwave frequencies is used to measure the band mass (m_b) of the two-dimensional holes (2DH's) in carbon-doped (100) GaAs/AlxGa1-xAs heterostructures. The…
Large Bychkov-Rashba spin-orbit coupling in high-mobility GaN/AlGaN heterostructures
S. Schmult, M. J. Manfra, A. Punnoose +3
We present low temperature magnetoconductivity measurements of a density-tunable and high mobility two-dimensional electron gas confined in the wide bandgap GaN/AlGaN system. We ob…
Reentrant anisotropic phases in a two-dimensional hole system
M. J. Manfra, Z. Jiang, S. H. Simon +3
Anisotropic charge transport is observed in a two-dimensional (2D) hole system in a perpendicular magnetic field at filling factors nu=7/2 and nu=11/2 for temperatures below 150mK.…
