Terahertz band-gap in InAs/GaSb type-II superlattices

Journal Article


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.
