Mid-infrared absorption by short-period InAs/GaSb type II superlattices

Journal Article


Abstract


  • We present a theoretical study on optical properties of short-period InAs/GaSb type-II superlattices

    (SLs) which can serve for mid-infrared (MIR) detection. The miniband structure of such SLs is calculated

    using the Kronig-Penney model. On the basis of the energy-balance equation derived from the

    Boltzmann equation we calculate the optical absorption coefficient. The obtained results agree with

    recent experimental findings. Moreover, the dependence of the MIR absorption in InAs/GaSb type-II SLs

    on temperature and well-widths are examined.
