Interaction and disorder in bilayer counterflow transport at filling factor one
E. Tutuc, M. Shayegan
We study high mobility, interacting GaAs bilayer hole systems exhibiting counterflow superfluid transport at total filling factor . As the density of the two layers is reduced…
Anomalous Spin Polarization of GaAs Two-Dimensional Hole Systems
R. Winkler, E. Tutuc, S. J. Papadakis +4
We report measurements and calculations of the spin-subband depopulation, induced by a parallel magnetic field, of dilute GaAs two-dimensional (2D) hole systems. The results reveal…
Ballistic transport in AlAs two-dimensional electrons
O. Gunawan, Y. P. Shkolnikov, E. P. De Poortere +2
We report the observation of commensurability oscillations in an AlAs two-dimensional electron system where two conduction-band valleys with elliptical in-plane Fermi contours are…
Critical Resistance of the Quantum Hall Ferromagnet in AlAs 2D Electrons
E. P. De Poortere, E. Tutuc, M. Shayegan
Magnetic transitions in AlAs two-dimensional electrons give rise to sharp resistance spikes within the quantum Hall effect. Such spikes are likely caused by carrier scattering at m…
