Effective mass suppression upon complete spin-polarization in an isotropic two-dimensional electron system
T. Gokmen, Medini Padmanabhan, K. Vakili +2
We measure the effective mass (m*) of interacting two-dimensional electrons confined to a 4.5 nm-wide AlAs quantum well. The electrons in this well occupy a single out-of-plane con…
Two-dimensional electrons occupying multiple valleys in AlAs
M. Shayegan, E. P. De Poortere, O. Gunawan +3
Two-dimensional electrons in AlAs quantum wells occupy multiple conduction-band minima at the X- points of the Brillouin zone. These valleys have large effective mass and g-factor…
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 susceptibility of two-dimensional electrons in narrow AlAs quantum wells
K. Vakili, Y. P. Shkolnikov, E. Tutuc +2
We report measurements of the spin susceptibility in dilute two-dimensional electrons confined to a 45 wide AlAs quantum well. The electrons in this well occupy an out-of-plane…
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…
Magnetic Field Induced Spin Polarization of AlAs Two-dimensional Electrons
E. P. De Poortere, E. Tutuc, Y. P. Shkolnikov +2
Two-dimensional (2D) electrons in an in-plane magnetic field become fully spin polarized above a field B_P, which we can determine from the in-plane magnetoresistance. We perform s…
