耦合量子点体系可以在激发态实现逆电性.在外电场中,耦合量子点产生极化.通过光激发,其感应电偶极矩反转.这种光电开关效应是一种新的光致现象
The coupled quantum dot system can achieve the inverse electric property in the excited state, and in the external electric field, the coupled quantum dot generates polarization, and the photoelectrical switching effect is a new photophoto phenomenon by photoexcitation
