New infrared detector materials with high sensitivity, multi-spectral capability, improved uniformity and lower manufacturing costs are required for numerous infrared sensing applications. One material system has shown great theoretical and experimental promise for these applications: InAs/InxGa1KxSb type-II superlattices. These superlattices offer a large(More)
Gallium (Ga)-free InAs/InAsSb superlattices (SLs) are being actively explored for infrared detector applications due to the long minority carrier lifetimes observed in this material system. However, compositional and dimensional changes through antimony (Sb) segregation during InAsSb growth can significantly alter the detector properties from the original(More)
