Parallel Magnetic Field Tuning of Valley Splitting in AlAs Two-Dimensional Electrons
T. Gokmen, Medini Padmanabhan, O. Gunawan +4
We demonstrate that, in a quasi-two-dimensional electron system confined to an AlAs quantum well and occupying two conduction-band minima (valleys), a parallel magnetic field can c…
Enhancement of valley susceptibility upon complete spin-polarization
Medini Padmanabhan, T. Gokmen, M. Shayegan
Measurements on a two-dimensional electron system confined to an AlAs quantum well reveal that for a given electron density the valley susceptibility, defined as the change in vall…
Dependence of Effective Mass on Spin and Valley Degrees of Freedom
T. Gokmen, Medini Padmanabhan, M. Shayegan
We measure the effective mass (m*) of interacting two-dimensional electrons confined to an AlAs quantum well while we change the conduction-band valley occupation and the spin pola…
Effective mass suppression in dilute, spin-polarized two-dimensional electron systems
Medini Padmanabhan, T. Gokmen, N. C. Bishop +1
We report effective mass (m*) measurements, via analyzing the temperature dependence of the Shubnikov-de Haas oscillations, for dilute, interacting, two-dimensional electron system…
