Antimonide-based Type-II superlattices (T2SL) are capable of delivering highly capable infrared detection capability. Improvement in material quality and processing techniques, as well as evolutionary modifications in device architecture have demonstrated the advantages of the material system over alternatives, and proven it as a viable candidate for the next generation infrared detection. Yet, th ...

STTR Phase I Uncertainty Quantification (UQ) technical feasibility demonstration using advanced mathematical techniques and Biologically Inspired Computing Architecture (BICA) concepts is proposed for Phase II prototype development. UQ in complex System of Systems (SoS) M & S environments is emphasized in Phase II. Graph theory based M & S techniques are explored that enhance and facilitate topi ...

This proposal examines innovative approaches and technologies that can be used to evaluate legacy models and simulations, determine the feasibility of porting them to multi-core simulation environments, and enable the legacy model capabilities to efficiently execute in such multi-core environments. We will employ Discrete Event System Specification (DEVS) Simulator architectures to support highly ...

American Energy Technologies Co. (a woman-owned small business concern of Arlington Heights, IL), will be joined by subcontractors University of Massachusetts (Boston, MA) and Advanced Technology Laboratories of Lockheed Martin Corp. (St. Paul, MN) in order to develop two anti-corrosion technologies with the goal to deploy them in a variety of equipment. The first technology is a top coating whic ...

Hydrogen isotopes have been shown to reduce the electrical effects of various semiconductor defects. Specifically, monoatomic hydrogen and deuterium passivate the electrical activity of defects such as dislocations in long-wavelength HgCdTe grown on Si. We propose a novel method of controlling the intake of hydrogen in HgCdTe IRFPAs by using the H2/He plasma afterglow formed by flowing plasma-gene ...

Current state-of-the-art infrared focal plane arrays (IRFPAs) are based on HgCdTe material epitaxially grown on bulk CdZnTe substrates. The size of the IRFPAs is limited by the size of the available CdZnTe substrates and the thermal mismatch between CdZnTe and the Si readout circuit, which misaligns the photodiode array with respect to the circuit during heating and cooling cycles. Having HgCdTe ...

Current state-of-the-art infrared focal plane arrays are based on HgCdTe grown on bulk CdZnTe substrates. The use of Si-based substrates would eliminate a number of drawbacks related to the HgCdTe/CdZnTe system and permit larger formats. We have developed growth protocols that produce material with good crystal quality for such a highly mismatched heteroepitaxial system. Double crystal rocking c ...

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 m ...
