Research Institution
Type II InAs/GaSb strained layer superlattices represent the most promising material system capable of delivering large format, reduced pixel pitch, long-wavelength infrared (LWIR) focal plane arrays (FPAs) for persistent surveillance applications. 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 passivation of this material is further complicated by the narrow separation between mesas necessary to realize reduced pixel pitch arrays. The objective of the proposed project is to develop effective passivation for large format reduced pixel pitch arrays of LWIR Type-II detectors.
