制备了具有巨磁光特性的半导体量子点(QD)与稀磁半导体(DMS)的磁性混杂结构。自旋极化的电子在DMS中被光学产生,然后通过量子隧道(自旋注入)转移到非磁性量子点中。量子点中电子的自旋态在时间上是守恒的,并通过圆偏振光致发光读出。
英文摘要
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.
