Electronic and optical properties of InAs/InAs${}_{0.625}$Sb${}_{0.375}$ superlattices and their application to far-infrared detectors

Ghulam Hussain, Giuseppe Cuono, Rajibul Islam +4

We calculate the electronic and optical properties of InAs/InAs${}_{0.625}$Sb${}_{0.375}$ superlattices within relativistic density functional theory. To have a good description of the…
