In Phase I we developed a novel infrared photodiode based on Type-II InAs/GaSb strained layer superlattices (SLS) that showed pingpong dualband action, wherein the spectral response of the diode was switched between extended midwave (~ 8 micron cutoff) and longwave (~ 10 micron cutoff) infrared by the polarity of the voltage bias applied across it. In Phase II we will improve quantum efficiency i ...

Thermal batteries are a power source for most MDA weapons systems. Some of these applications place severe constraints on battery weight and size. The key components of thermal batteries are typically made by hydraulically pressing powders into"pellets". The pellets must be greater than a minimum thickness to avoid breakage, and for batteries that must supply high current for a short time this ...

"SSSC is pleased to propose the development and delivery of a Hostile Fire Indication Sensor (HFIS) based on the Phase I design concept. The resulting system will limit the number of circuit card assemblies to two: one for the short wave infrared (SWIR)

THE NUCLEAR REGULATORY COMMISSION (NRC) HAS SPONSORED THE DEVELOPMENT OF THE NUCLEAR PLANT DATA BANK (NPDB) SYSTEM AT TECHNOLOGY DEVELOPMENT OF CALIFORNIA (TDC) FOR APPROXIMATELY THE LAST FIVE YEARS. THIS WORK IS ESSENTIALLYCOMPLETE AND IS AN INTEGRAL PART OF THE NUCLEAR PLANT A (NPA). TO MAKE THE NPDB A USEFUL AND PRODUCTIVE SYSTEM, REPRESENTATIVE DESCRIPTIONS OF NUCLEAR POWER PLANTS MUST BE ENTE ...

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 ...
