Dependence of persistent gaps at Landau level crossings on relative spin
K. Vakili, T. Gokmen, O. Gunawan +3
We report measurements of the quantum Hall state energy gap at avoided crossings between Landau levels originating from different conduction band valleys in AlAs quantum wells. The…
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…
Spin-dependent resistivity at transitions between integer quantum Hall states
K. Vakili, Y. P. Shkolnikov, E. Tutuc +3
The longitudinal resistivity at transitions between integer quantum Hall states in two-dimensional electrons confined to AlAs quantum wells is found to depend on the spin orientati…
Thermopower of Interacting GaAs Bilayer Hole Systems in the Reentrant Insulating Phase near
S. Faniel, E. Tutuc, E. P. De Poortere +5
We report thermopower measurements of interacting GaAs bilayer hole systems. When the carrier densities in the two layers are equal, these systems exhibit a reentrant insulating ph…
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…
Realization of an Interacting Two-Valley AlAs Bilayer System
K. Vakili, Y. P. Shkolnikov, E. Tutuc +2
By using different widths for two AlAs quantum wells comprising a bilayer system, we force the X-point conduction-band electrons in the two layers to occupy valleys with different…
