Quenching of the electronic spin relaxation and decoherence by localization on donors
Résumé
In pump-probe experiments, we compare the spin relaxation and decoherence times of electrons bound on neutral donors inside an intrinsic CdTe quantum well (QW), with those of free electrons in a doped CdTe QW. We demonstrate that the localization of the electrons on donors, slows down the spin relaxation and the spin decoherence by two orders of magnitude.
