We carried out a detailed calculation of quadratic electro-optic effects(QEOE)and electro-absorption process(EA) on a ZnS/CdSe core-shell quantum dot as a function of pump photon energy with different incident photon energy and under different quantum dot size.
在有效质量近似下,利用量子力学的密度矩阵理论,采用无限深势阱模型,从理论上计算了考虑极化子效应后在导带子带间跃迁时ZnS/CdSe柱型核壳结构量子点二次电光效应(QEOE)和电吸收过程(EA)的三阶极化率。
