| 英文摘要 | A comparative study of the steady-state and transient optical properties was made between ingaas/gaas quantum do chains (qdcs) and quantum dots (qds). it was found that the photoluminescence (pl) decay time of qdcs exhibited a strong photon energy dependence, while it was less sensitive in qds. the pl decay time increased much faster with the excitation power in the qdcs than that in qds. when the excitation power was large enough, the pl decay time tended to be saturated. in addition, it was also found that the pl rise time was much shorter in qdcs than in qds. all these experimental results show that there is a strong carrier coupling along the chain direction in the qd chain structure. the polarization pl measurements further confirm the carrier transfer process along the chain direction. |
