Abstract

We demonstrate theoretically that it is possible to realize terahertz (THz) fundamental band-gap in InAs/GaSb type-II superlattices (SLs). The presence of such band-gap can result in a strong cut-off of optical absorption at THz bandwidth. This study is pertinent to the application of InAs/GaSb type-II SLs as THz photodetectors.
