Tuning of the spin-orbit interaction in two-dimensional GaAs holes via strain
B. Habib, J. Shabani, E. P. De Poortere +2
We report direct measurements of the spin-orbit interaction induced spin-splitting in a modulation-doped GaAs two-dimensional hole system as a function of anisotropic, in-plane str…

AlAs 2D electrons in an antidot lattice: Electron pinball with elliptical Fermi contours
O. Gunawan, E. P. De Poortere, M. Shayegan
We report ballistic transport measurements in a two-dimensional electron system confined to an AlAs quantum well and patterned with square antidot lattices of period 0.6, 0.8…

Two-dimensional electrons occupying multiple valleys in AlAs
M. Shayegan, E. P. De Poortere, O. Gunawan +3
Two-dimensional electrons in AlAs quantum wells occupy multiple conduction-band minima at the X- points of the Brillouin zone. These valleys have large effective mass and g-factor…
