kink band
解釋
急折帶-
Referring to the formation process of qd, it is accepted that there formed a groove around the dot during the formation process due to mass - transfer. when the dots were capped by a compound with larger band gap, there will appear a potential maximum due to larger confinement. the maximum will prevent the carriers from entering the dot, and the origin of the kink point is resulted from the prevention
根據s - k模式量子點的形成過程,我們認為在點的形成過程中由於質量遷移會在點的周圍形成一個凹槽,加上覆蓋層后,由於大的量子限域效應該處將形成一個勢能極大值,該勢能極大值將阻礙載流子從勢壘層向量子點的注入,該過程是導致上述拐點出現的原因。
