Absorber layers based on strained layer superlattice (SLS) composed of III-V compound semiconductors (e.g. GaSb and InAs/Sb) are a promising sensor technology for infrared imaging; however, dark currents and short carrier lifetimes in SLS are still significant problems. It is presently suspected that the short carrier lifetimes and some dark current arise due to a native point defect, possibly the ...

High performance HgCdTe infrared detector arrays operating at 77 K can be tailored for response across the infrared spectrum (1 to 14 micron and beyond), and are utilized in a variety of military and civilian systems for infrared imaging. Reducing cooling requirements allows integration in lighter and more compact systems. Good performance at higher operating temperatures can be provided by a syst ...

Two-electron reduced-density-matrix (2-RDM) methods represent all of the electrons in any molecule or material with only two electrons by replacing the wave function by the 2-RDM as the basic variable for quantum many-electron theory. The 2-RDM methods, developed by David Mazziotti at The University of Chicago with support from the Army Research Office, have polynomial scaling with system size, al ...

Computer-aided analysis of electromagnetic field interactions with complex platforms housing multiple communication and computing electronics is a computational task of formidable and often prohibitive complexity. Yet, such an analysis is of significant technological importance since it offers the means to quantify the susceptibility of the platform and its electronics to external electromagnetic ...

Metal-organic frameworks (MOFs) are high-potential adsorbents for toxic chemical remediation, energy storage, air separation, and multiple other military and civilian applications. However, the utility of these materials is limited by existing production economics. A scalable production process is required for the adoption of this material class into next-generation gas adsorption systems. Furthe ...

To address the Army's need for the compact high resolution hemispherical imaging system, Distant Focus Corporation (DFC) proposes to develop Hemispherical Imaging Monocentric Optics System (HIMOS). The HIMOS architecture is based on innovative and recently developed virtual stop monocentric lens concept. This innovative architecture makes DFC HIMOS system extremely compact by having excellent imag ...

The objective for Phase II is to transition the nanopatterning results obtained in Phase I to epitaxial lift-off (ELO)-based GaAs cells. By developing nanopatterning on ELO solar cells and antireflection coatings and by laminating the cells using nanopatterned PET/Teflon films, we can develop highly flexible and lightweight solar cells that are less sensitive to the angle of incidence of incoming ...

During its Phase I SBIR research and development efforts Hy-Tek Mfg. Co. Inc. (HMC) designed, fabricated and demonstrated an innovative technology devised specifically to achieve the U.S. Army's CSS water vapor reclamation goals, including:CSS Water Va

The objective of this project is to build on the successful feasibility studies of Phase I to develop and to start commercialization of a new FE/MBS software that allows for the integration of computational geometry methods. This code will be designed to meet DOD and industry needs for the simulation of complex engineering and physics systems including vehicle system models with significant detail ...
