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…
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…
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…
Field-Effect Persistent Photoconductivity
E. P. De Poortere, Y. P. Shkolnikov, M. Shayegan
We report a persistent increase or decrease in the two-dimensional electron density of AlAs or GaAs quantum wells flanked by AlGaAs barriers, brought about by illuminating the samp…
