Optically-detected long-lived spin coherence in multilayer systems: Double and triple quantum wells
S. Ullah, G. M. Gusev, A. K. Bakarov +1
In this contribution, we investigated the spin coherence of high-mobility dense two-dimensional electron gases confined in multilayer systems. The dynamics of optically-induced spi…
Tailoring multilayer quantum wells for spin devices
S. Ullah, G. M. Gusev, A. K. Bakarov +1
The electron spin dynamics in multilayer GaAs/AlGaAs quantum wells, containing high-mobility dense two-dimensional electron gases, have been studied using time-resolved Kerr rotati…
Robustness of spin coherence of the exciton bound to neutral donor states in multilayer system
S. Ullah, F. C. D. Moraes, G. M. Gusev +2
We address the temperature influence on the precessional motion of electron spins under transverse magnetic field, studied in a GaAs/AlGaAs triple quantum wells, using pump-probe K…
Large anisotropic spin relaxation time of exciton bound to donor states in triple quantum wells
S. Ullah, G. M. Gusev, A. K. Bakarov +1
We have studied the spin dynamics of a dense two-dimensional electron gas confined in a GaAs/AlGaAs triple quantum well by using time-resolved Kerr rotation and resonant spin ampli…
Long-lived nanosecond spin coherence in high-mobility 2DEGs confined in double and triple quantum wells
S. Ullah, G. M. Gusev, A. K. Bakarov +1
We investigated the spin coherence of high-mobility two-dimensional electron gases confined in multilayer GaAs quantum wells. The dynamics of the spin polarization was optically st…
