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…
