| Research Abstract |
Inter-well transfer of excitons was studied by using multi quantum well (MQW) structures consisting of a diluted magnetic semiconductor (DMS) well and nonmagnetic semiconductor (NMS) wells. Exciton transfer from DMS well to NMS well was confirmed by observing degree of circular polarization of photoluminescence from NMS well. Exciton transfers from DMS well to the next NMS well and to the next-but-one NMS well were separately observed in MQW samples with a novel structure.
