Charge-carrier transfer (CT) from the perovskite host to PbS QDs were studied using fs-transient absorption and THz techniques. The CT rate constants increase with the size of QDs due to a change in the position of valence and conduction bands in PbS QDs.

Carrier Transfer

By fabricating graphene/Bi2Te3 heterojunction, the mechanism of carrier-transfer resulting in enhanced optical nonlinearity was investigated. The rapid over-saturation of Bi2Te3 is solved and a better performance is acquired in Q-switched laser.
