摘要

数值证实了三阶光磁化率χ(3)(ω; -ω,ω, -ω)在CuCl量子球(QS’s)中被介观增强的激子跃迁偶极矩所增强,但在GaAs量子球(QS’s)中没有,在CdS量子球(QS’s)中是边缘的。

Excitonic Optical Nonlinearity in Semiconductor Quantum Spheres
It is numerically confirmed that the third-order optical susceptibility χ(3)(ω;–ω,ω,–ω) is enhanced by the mesoscopically enhanced transition dipole moment of excitons in CuCl quantum spheres (QS's) but it is not in GaAs QS's and it is marginal for CdS QS's.
