STUDY OF INTERSUBBAND OPTICAL TRANSITIONS IN GaAs/AlxGa1-xAs SUPERLATTICES
GaAs/AlxGa1-xAs超晶格子带间光跃迁的研究

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.
