Global Technology Connection, Inc., in collaboration with academic partners, Georgia Tech"s Center for Innovative Battery and Fuel Cell Technologies, Penn State University, and industrial partner Eagle Picher propose to create a physics-based modeling for predicting the life performance of Low and Middle Earth Orbit (LEO/MEO) Lithium-ion cells. The relationships between solid-electrolyte interpha ...

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 ...

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 ...

Recent development of Antimonide-based Type-II superlattice infrared detectors has resulted in significant breakthroughs in terms of device performance as well as FPA imaging quality. Improvement in material quality and processing technique, as well as evolutionary modifications in device architecture have demonstrated the advantages of the material system over alternatives, and proven it as a via ...

For many applications, there is a need for developing inertial measurement units (IMU), employing gyroscopes and accelerometers, with better accuracy and/or smaller volume and weight. Currently, in partnership with others, we at Digital Optics Technologies (DOT) have been developing a superluminal ring laser gyroscope (SRLG) that can improve the accuracy of rotation sensing by nearly five orders ...

High performance single-band focal plane arrays (FPAs) are sometimes unable to discriminate a target from its background when they present similar infrared radiation at a given wavelength which may occur even if the temperatures of the objects are different. Two-Color FPAs offer an additional wavelength that allows easy identification in such cases. Large-format dual-band FPAs are highly needed f ...

High-performance detectors sensing in the long wavelength and very long wavelength infrared spectral ranges are desirable for various applications supporting Air Force and Missile Defense capabilities. Limited types of detectors and arrays are currently available for the detection of infrared radiation with wavelengths longer than 15 microns, and most are based on low quantum efficiency extrinsic ...

We propose a new generation of non-equilibrium, high efficiency long and very long wavelength infrared (8 microns and longer) superlattice-based detectors that operate in the 40 to 77 K temperature range. This technology will lead to the possibility of improving the performance of current infrared focal plane arrays. It will also permit the creation of very long wavelength infrared detection capab ...

EPIR Technologies has experience in polishing II-VI semiconductor substrates for MBE applications. We propose to transfer this experience to the polishing of Sb-based substrates. The quality of a surface is determined by the degree of surface flatness (or curvature), smoothness, stoichiometry, and the magnitude of surface/sub-surface damage. All these parameters are addressed in this proposal. ...
