Research Institution
Infrared photon sensors presently available for ballistic missile defense applications, with a cutoff wavelength ~10 micron, are based on HgCdTe. These suffer from a high non-uniformity and thus a high focal plane array cost. The most promising alternative is III-V compound semiconductor superlattices based on arsenides and antimonides, such as Type-II InAs/GaSb superlattices, which are expected to exhibit higher quantum efficiency and uniformity than current systems. This Phase II project plans to capitalize on previous Phase I and Phase II efforts, integrating them in order to advance the technology for Type-II InAs/GaSb superlattices in order to demonstrate and deliver prototype 256x320 focal plane arrays with an ~10 micron cutoff wavelength. This improved device will incorporate a hybrid M-structure – double-heterostructure design for significantly improved R0A and overall device performance.
