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…
Anomalous Spin Polarization of GaAs Two-Dimensional Hole Systems
R. Winkler, E. Tutuc, S. J. Papadakis +4
We report measurements and calculations of the spin-subband depopulation, induced by a parallel magnetic field, of dilute GaAs two-dimensional (2D) hole systems. The results reveal…
Thermopower of Interacting GaAs Bilayer Hole Systems in the Reentrant Insulating Phase near
S. Faniel, E. Tutuc, E. P. De Poortere +5
We report thermopower measurements of interacting GaAs bilayer hole systems. When the carrier densities in the two layers are equal, these systems exhibit a reentrant insulating ph…
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…
A Laterally Modulated 2D Electron System in the Extreme Quantum Limit
Sorin Melinte, Mona Berciu, C. Zhou +9
We report on magnetotransport of a two-dimensional electron system (2DES), located 32 nm below the surface, with a surface superlattice gate structure of periodicity 39 nm imposing…
