Abstract
The physical properties of InAsSb strained-layer superlattices are reviewed. After a brief description of the band structure and superlattice growth and characterization, we present infrared absorption results and demonstrate the first device made from these materials, a p-n junction photodiode. From these studies, we find that these new materials can be designed to absorb out into the far infrared, well beyond the bandgap of any bulk III-V material. The prototype, non-optimized photodiode displayed a detectivity at 7 pm that is within one order of magnitude of the detectivity of the best HgCdTe detectors at that wavelength.
