The spin dynamics of localized donor-bound electrons interacting with the nuclear spin ensemble in $n$-doped GaAs epilayers is studied using nuclear spin polarization by light with modulated circular polarization. We show that the observed build-up o

Diffusive Propagation of Exciton-Polaritons through Thin Crystal Slabs

Autor: Zaitsev, D. A., Ilinskaya, N. D., Koudinov, A. V., Poletaev, N. K., Egorov, A. Yu., Kavokin, A. V., Seisyan, R. P.

Comparative studies of the resonant transmission of light in the vicinity of exciton resonances, measured for 15 few-micron GaAs crystal slabs with different impurity concentrations $N$, reveal an unexpected tendency. While $N$ spans almost five deci

Suppression of Dyakonov-Perel Spin Relaxation in high mobility n-GaAs

Autor: Dzhioev, R. I., Kavokin, K. V., Korenev, V. L., Lazarev, M. V., Poletaev, N. K., Zakharchenya, B. P., Stinaff, E. A., Gammon, D., Bracker, A. S., Ware, M. E.

We report a large and unexpected suppression of the free electron spin relaxation in lightly-doped n-GaAs bulk crystals. The spin relaxation rate shows weak mobility dependence and saturates at a level 30 times less then that predicted by the Dyakono
