InAsSb strained-layer superlattices (SLS's) are proposed as novel III-V semiconductor materials with the potential for long wavelength intrinsic detector applications. Theoretical studies indicate that the wavelength cutoff of InAs/sub 0/ /sub 4/Sb/sub 0/ /sub 6//InAs/sub 1-y/Sb/sub y/SLSs with y> 0.73 can be extended to 12 ..mu..m at 77K through the intentional use of layer strains. These new materials may avoid many of the growth and stability problems associated with HgCdTe and may lead to more reproducible and dependable long-wavelength ir arrays. This work builds upon successful SLS ir detector studies that have been performed in the InGaAs/GaAs material system.
