Spin Orientation of Holes in Quantum Wells (2008)
Winkler, R., Culcer, Dimitrie, Papadakis, S. J., Habib, B., Shayegan, M.
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 their counterparts in...
Anisotropic low-temperature piezoresistance in (311)A GaAs two-dimensional holes (2007)
Habib, B., Shabani, J., De Poortere, E. P., Shayegan, M., Winkler, R.
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 but anisotropic...
Strong Aharonov-Bohm oscillations in GaAs two-dimensional holes (2006)
Habib, B., Tutuc, E., Shayegan, M.
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 oscillations is about 10% of...
Tuning of the spin-orbit interaction in two-dimensional GaAs holes via strain (2006)
Habib, B., Shabani, J., De Poortere, E. P., Shayegan, M., Winkler, R.
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 strain. The change in...
Dephasing Time of Two-Dimensional Holes in GaAs Open Quantum Dots (2006)
Faniel, S., Hackens, B., Vlad, A., Moldovan, L., Gustin, C., Habib, B., ...
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 temperatures $T$ below 500 mK,...
Quantized conductance in an AlAs 2D electron system quantum point contact (2006)
Gunawan, O., Habib, B., De Poortere, E. P., Shayegan, M.
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 elliptical Fermi...

La méthode de calcul Monte Carlo est reconnue aujourd'hui comme l'algorithme pouvant modéliser au plus près les phénomènes physiques liés aux dépôts d'énergie dans un milieu. Il est donc...

Spin Splitting in GaAs (100) Two-Dimensional Holes (2004)
Habib, B., Tutuc, E., Melinte, S., Shayegan, M., Wasserman, D., Lyon, S. A., ...
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 oscillations contains...
Negative differential Rashba effect in two-dimensional hole systems (2004)
Habib, B., Tutuc, E., Melinte, S., Shayegan, M., Wasserman, D., Lyon, S. A., ...
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 with...
