利用时间分辨相干双光子激发和探测技术,在时间域内研究了激子极化子的本征退相时间。这种方法可以区分半导体中激子极化子的基本相互作用过程。在CuCL中得到的结果显示了不同声子在激子-极化激子退相中的作用
The intrinsic dephasing time of an exciton polariton is investigated in the time domain by use of a time-resolved coherent two-photon excitation and probe technique. This method allows discrimination of the elementary interaction processes of the exciton polariton in semiconductors. The results obtained in CuCl show the role of the different phonons in the exciton-polariton dephasing
