Spectrum of GaSb tetrahedral QD lattice

The following tutorial based on that article:

Laghumavarapu, R. B., et al. “Ga Sb/ Ga As type II quantum dot solar cells for enhanced infrared spectral response.” Applied Physics Letters 90.17 (2007): 173125.

The GaSb tetrahedral quantum dots are embedded in a GaAs matrix, with base length $30 nm$ and height $7nm$. The band structure is calculated considering strain, in k.p 8 band framework.

The calculated absorption spectrum without considering the superlattice dispersion is plotted in figure 1.
