摘要
运用Kronig-Penney模型的新形式,研究了超晶格子带间光跃迁的频率、带宽和跃迁强度,用GaAs/Al_xGa_(1-x)As多量子阱材料做了关于红外吸收的实验,理论与实验符合较好。
In this article, we investigate the properties (transition frequency, bandwidth, and dipole transition moment) of intersubband optical transitions by using the new general form of the Kronig-Penney model developed recently. The theoretical results are in good agreement with our experimental measurements of infrared absorption in a GaAs/AlxGa1-xAs superlattice.
