Spin Orientation of Holes in Quantum Wells
R. Winkler, Dimitrie Culcer, S. J. Papadakis +2
This paper reviews the spin orientation of spin-3/2 holes in quantum wells. We discuss the Zeeman and Rashba spin splitting in hole systems that are qualitatively different from th…
Anisotropic low-temperature piezoresistance in (311)A GaAs two-dimensional holes
B. Habib, J. Shabani, E. P. De Poortere +2
We report low-temperature resistance measurements in a modulation-doped, (311)A GaAs two-dimensional hole system as a function of applied in-plane strain. The data reveal a strong…
Strong Aharonov-Bohm oscillations in GaAs two-dimensional holes
B. Habib, E. Tutuc, M. Shayegan
We measured Aharonov-Bohm resistance oscillations in a shallow two-dimensional GaAs hole ring structure, defined by local anodic surface oxidation. The amplitude of the oscillation…
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…
Dephasing Time of Two-Dimensional Holes in GaAs Open Quantum Dots
S. Faniel, B. Hackens, A. Vlad +6
We report magnetotransport measurements of two-dimensional holes in open quantum dots, patterned either as a single-dot or an array of dots, on a GaAs quantum well. For temperature…
Quantized conductance in an AlAs 2D electron system quantum point contact
O. Gunawan, B. Habib, E. P. De Poortere +1
We report experimental results on a quantum point contact (QPC) device formed in a wide AlAs quantum well where the two-dimensional electrons occupy two in-plane valleys with ellip…
