Light absorption in semiconducting quantum dot clusters with fixed surface areas in an external tilted magnetic field
Source abstract
Abstract
In the present study, we theoretically investigate the far infrared (FIR) spectrum of clusters formed by AlxGa1−xAs/GaAs, GaN/AlN, InSb/GaSb, and ZnSe/CdSe semiconductor hetero-structure quantum dots (QDs). The clusters are obtained by circle packing disc-shaped QDs in a square domain. The close spacing effect has previously been observed by experiment. For a given square area, we analyze the effects of the externally applied magnetic field (intensity and direction) on the FIR absorption coefficient for different QD packing values. The finite difference method is used to solve the two-dimensional Schrödinger equation describing the QD clusters in magnetic fields.
