Longwave infrared focal plane arrays (FPAs) based on Type-II InAs/GaSb-based strained layer superlattice (SLS) photodiodes show good performance at the current time. A key remaining challenge is the reduction of dark current, dominated by pixel surface leakage in FPAs and low minority carrier lifetime in the bulk material. We propose to address the former in this Phase I and develop a unique sche ...

We propose to develop Co-located Triple Band Quantum Well Infrared Photodetectors (QWIP) Arrays. The innovative features are: Co-located Triple Band Structure The detection of short waveband (0.7-2.micro.m) midwaveband (3-5.micro.m) and long waveband (8-13.micro.m) signals takes in the same pixel (Co-located pixel). Simultaneous Detection of 3-Color Signals The design is such that detection of 3- ...

Next generation high performance electromechanical actuators will enable the fabrication of new military and commercial devices. Traditionally, the piezoelectric and electrostrictive effects of ferroelectric ceramics have been exploited to fabricates electromechanical actuators. These ceramic materials are technically very mature, are relatively dense, suffer form low field-induced strain, and t ...

This proposal advocates the use of CMOS circuits with aggressively scaled supply and threshold voltages to design low threshold voltage systems (LVTS) for low power digital applications. The program proposes to generate a CMOS cell library designed around n-channel and p-channel MOS transistors designed to operate at zero threshold voltage, VT=O, using back bias to compensate for process and envir ...
