Cheaper and higher performance infrared sensors are needed for next generation ballistic missile defense programs. Type II InAs/GaSb superlattices represent the most promising material system capable of delivering a more manufacturable and affordable focal plane array technology than the current technology, while at the same time exhibiting similar or better performance. At present, one of the most significant hurdles to overcome is to enhance the noise performance of such detectors through proper surface passivation of such structures. The objective of the proposed Phase II will be to develop effective passivation techniques and realize a prototype Type II superlattice array with enhanced performance in terms of reduced leakage current and uniformity.
