| 摘 要： | ZnO是具有3.37 eV的宽禁带半导体材料,近年来引起了众多研究者的兴趣。Zn1-xCdxO和Zn1-xMgxO很好地实现了对ZnO能带的减小和增大。采用较为简单的一维K P势模型结合有效质量理论得到了ZnO/Zn1-xCdxO及ZnO/Zn1-xMgxO多量子阱的能量色散关系,以及子带的MeV跃迁与超晶格带阶、阱垒宽度之间的关系。将该多量子阱应用于太赫兹量子级联激光器(THz QCL)有源区,对粒子数反转和跃迁矩阵进行了相关讨论。

| Abstract: | ZnO has become more and more popular because of its wide bandgap of 3.37 eV. Zn1-xCdxO and Zn1-xMgxO have well realized the decreasement and increasement of ZnO bandgap. Using a simple 1-D K?P potential model combined with the effective mass theory, energy dispersion relation of multiple quantum wells and the relationship among intersubband transition, superlattice band offset and well/barrier width are obtained. Applying the multiple quantum well to the active area of Terahertz Quantum Cascade Laser(THz QCL), the population inversion and transition matrix are discussed. |
