非对称耦合双量子阱的荧光光谱研究

STUDY OF THE PL SPECTRA OF ASYMMETRIC COUPLED DOUBLE QUANTUM WELLS

讨论了耦合双量子阱的光荧光性质，并着重对不同垒宽样品的荧光性质与激发功率的关系进行了详细讨论。

The PL properties of asymmetric coupled double quantum wells (ACDQW) structures were studied.The dependence of nonresonant tunneling rate on excitation power for different interbarrier thickness was discussed in detail.The competition between the intersubband relaxations was analyzed.
