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…
Spin Polarization Dependence of the Coulomb Drag at Large
R. Pillarisetty, H. Noh, E. Tutuc +3
We find that the temperature dependence of the drag resistivity () between two dilute two-dimensional hole systems exhibits an unusual dependence upon spin polarization. Nea…
Spin susceptibility of two-dimensional electrons in narrow AlAs quantum wells
K. Vakili, Y. P. Shkolnikov, E. Tutuc +2
We report measurements of the spin susceptibility in dilute two-dimensional electrons confined to a 45 wide AlAs quantum well. The electrons in this well occupy an out-of-plane…
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…
Coulomb Drag near the metal-insulator transition in two-dimensions
R. Pillarisetty, H. Noh, E. Tutuc +4
We studied the drag resistivity between dilute two-dimensional hole systems, near the apparent metal-insulator transition. We find the deviations from the dependence of the…
