Theoretical and experimental study on infrared intersubband transitions of quantum wells
Abstract
The dependence of intersubband transition properties (transition frequency, bandwidth, and dipole transition moment) on the superlattice quantum potential parameters (well width, barrier width, and alloy composition) has been studied in this article by using the new general form of the Kronig-Penney model developed recently. The physical origin of the dependence is elucidated, and a comparison of the theoretical results with our experimental measurements of GaAs/A1 itxGa 1- xAs is also given.
