Abstract This article reports a study on quantum beat of excitons in spherical semiconductor quantum dots. With renormalized wavefunction formulation for a three-level model including ground state level and two excited ones of exciton, quantum beat of excitons is observed to be twice the electron Rabi frequency while a strong resonant pump laser is connecting two exciton excited levels. In addition, dependences of characteristics of quantum beat of excitons on dot radius and pump laser detuning are examined.

球形半导体量子点中激子的量子节拍

摘要 本文报道了球形半导体量子点中激子的量子节拍研究。对于包含基态能级和激子的两个激发能级的三能级模型的重整化波函数公式，观察到激子的量子拍频是电子 Rabi 频率的两倍，而强谐振泵浦激光器连接两个激子激发能级。此外，研究了激子的量子节拍特性对点半径和泵浦激光失谐的依赖性。
