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…
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…
Negative differential Rashba effect in two-dimensional hole systems
B. Habib, E. Tutuc, S. Melinte +4
We demonstrate experimentally and theoretically that two-dimensional (2D) heavy hole systems in single heterostructures exhibit a \emph{decrease} in spin-orbit interaction-induced…
Spin Splitting in GaAs (100) Two-Dimensional Holes
B. Habib, E. Tutuc, S. Melinte +4
We measured Shubnikov-de Haas (SdH) oscillations in GaAs (100) two-dimensional holes to determine the inversion asymmetry-induced spin splitting. The Fourier spectrum of the SdH os…
