摘要

我们研究了lo -声子级联发射在量子阱中的量子动力学，电子-空穴对的弛豫结束于量子点的捕获。以lo -声子频率为周期的调制在时间分辨微分透射谱中逐渐出现，表明从量子动力学到经典态的转变。

Coherent control and quantum kinetics of LO-phonon emission in CdZnTe quantum wells

We study the quantum kinetics of LO-phonon cascade emission in quantum wells by electron-hole pairs, whose relaxation ends with a trapping in quantum dots. Modulations with a period given by the LO-phonon frequency appear progressively in the time resolved differential transmission spectrum, indicating the transition from the quantum kinetic to the classical regime.
