A computational approach of optical absorption in semiconductor quantum dot superlattices

In this paper, a computational approach based on decoupled study for different directions in the analysis of minibands structure and absorption coefficient for cuboid quantum dot superlattices is described and used. Analysis is focused on zinc-blende semiconductors (such as InAs and GaAs) and wurtzite InGaN. Nowadays, the latter represents a promising material for light emission, but it could become an interesting semiconductor for devices based on optical absorption, too.
