Abstract
Bandgap and carrier dispersion in superlattices (SL) based on InAsSb can be precisely controlled by variation of the layer composition and width. However, when grown strain-balanced on GaSb, possible SL designs are seriously limited. The virtual substrate approach on the other hand removes this limitation thus opening a way to design SLs and QWs with non-generic electronic properties including Dirac carrier dispersion and topologically nontrivial states.
