量子阱中激子的光谱结构

Spectrums of quantum-well excitons

:探讨了量子阱中激子的光谱结构 ,在薛定谔表象下 ,使用拉氏变换 ,利用Wigner weisskoff近似 ,得出了体系随时间演变的波函数 .假定体系的初态为激子态时 ,得到了激子光谱的双峰结构 .当调节光场的频率时 ,可以得到双峰的对称和非对称结构 .

The spectrums of quantum-well excitons are studied. In Shrodinger representation, the wave function of this system is worked out with Laplace transforms and Wigner-Weisskoff approximation. If the system's initial state is exciton, the spectrums with tow peaks could be obtained.
