Investigation of high optical gain (MIR region) in AlSb/InAs/GaAsSb type-II quantum well heterostructure

A type-II (with broken bandgap) W-shaped nano-heterostructure having layers combination of AlSb, InAs and GaAsSb compound semiconductors has been proposed which can be utilized as high intensity lasing source in MIR (mid infrared region). For this heterostructure, a multiband band k.p Hamiltonian ha...
