Resistance Spikes at Transitions between Quantum Hall Ferromagnets
E. P. De Poortere, E. Tutuc, S. J. Papadakis +1
We report a new manifestation of first-order magnetic transitions in two-dimensional electron systems. This phenomenon occurs in aluminum arsenide quantum wells with sufficiently l…
In-plane magnetic field-induced spin polarization and transition to insulating behavior in two-dimensional hole systems
E. Tutuc, E. P. De Poortere, S. J. Papadakis +1
Using a novel technique, we make quantitative measurements of the spin polarization of dilute (3.4 to 6.8*10^{10} cm^{-2}) GaAs (311)A two-dimensional holes as a function of an in-…
Confinement symmetry, mobility anisotropy, and metallic behavior in (311)A GaAs 2D holes
S. J. Papadakis, E. P. De Poortere, M. Shayegan
We study two dimensional hole systems confined to GaAs quantum wells grown on the (311)A surface of GaAs substrates. Such samples exhibit an in-plane mobility anisotropy. At consta…
Spin-splitting in GaAs 2D holes
S. J. Papadakis, E. P. De Poortere, M. Shayegan +1
We present quantitative measurements and calculations of the spin-orbit induced zero-magnetic-field spin-splitting in two-dimensional (2D) hole systems in modulation-doped GaAs (31…
Highly anisotropic g-factor of two-dimensional hole systems
R. Winkler, S. J. Papadakis, E. P. De Poortere +1
Coupling the spin degree of freedom to the anisotropic orbital motion of two-dimensional (2D) hole systems gives rise to a highly anisotropic Zeeman splitting with respect to diffe…
