Observation of Quantum Hall Valley Skyrmions
Y. P. Shkolnikov, S. Misra, N. C. Bishop +2
We report measurements of the interaction-induced quantum Hall effect in a spin-polarized AlAs two-dimensional electron system where the electrons occupy two in-plane conduction ba…
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…
Giant low-temperature piezoresistance effect in AlAs two-dimensional electrons
Y. P. Shkolnikov, K. Vakili, E. P. De Poortere +1
We present piezoresistance measurements in modulation doped AlAs quantum wells where the two-dimensional electron system occupies two conduction band valleys with elliptical Fermi…
Low-temperature, in situ tunable, uniaxial stress measurements in semiconductors using a piezoelectric actuator
M. Shayegan, K. Karrai, Y. P. Shkolnikov +3
We demonstrate the use of a piezoelectric actuator to apply, at low temperatures, uniaxial stress in the plane of a two-dimensional electron system confined to a modulation-doped A…
Dependence of spin susceptibility of a two-dimensional electron system on the valley degree of freedom
Y. P. Shkolnikov, K. Vakili, E. P. De Poortere +1
We report measurements of the spin susceptibility, , in an AlAs two-dimensional electron system where, via the application of in-plane stress, we transfer elec…
