| Research Abstract |
Magnetic hybrid structures of semiconductor quantum dots (QDs) with diluted magnetic semiconductors (DMSs), indicating giant magneto-optical properties, were fabricated. Spin-polarized electrons were optically generated in the DMS and were subsequently transferred into non-magnetic QDs via quantum tunneling (spin injection). The spin states of the electrons were temporally conserved in the QDs and were also read-out by circularly polarized photoluminescence.
