This program is focused on growth of thick low doped Silicon Carbide epitaxial layers suitable for ultra-high voltage (10-15 kV) SiC bipolar power devices using improved epitaxial growth chemistries and reactor design. This Phase II STTR program will focus on extending the growth rates achieved in Phase I, and to realize epitaxial layers that alleviate VF drift in SiC bipolar devices. Reactor desi ...

Clear Science Corp. and the University of California at Los Angeles propose to develop a versatile and comprehensive computational toolbox for designing feedback flow controllers in aerodynamic applications. Target objectives include separation control to manage lift and drag, control of transition to turbulence, turbulence control to reduce skin friction drag, increase mixing, or reduce heat tra ...

This Phase II effort demonstrates the feasibility of integrating a chemically powered or “active” infrared (IR) treatment into an inflatable device and then perform three experimental excursions with the hardware: 1) achieve a tunable IR signature by cooling the surface; 2) achieve tunable IR emissions combined with a predetermined and fixed radar cross section (RCS); and 3) achieve both varia ...

This Phase II STTR research project is designed to further develop a mass spectrometry technology employing Hadamard Transform (HT) multiplexing techniques with the goal of developing a relatively simple, linear, rugged, HT time-of-flight (HT-TOF) mass spectrometer that offers high sensitivity and rapid mass spectra storage rates. Southwest Sciences and Stanford University will focus their effor ...

The development of a rapid and accurate personal identification system improves our nation’s capability in identifying potential terrorists and provides the most reliable means for securing government or private industry’s confidential or classified secrets. However, single biometric based applications have not been widely deployed due to the variation in accuracy and their inability to preve ...

Photonics research is increasingly focusing on integrated photonic chip platforms, built around photonic crystals, nanoscale devices and hybrid integration. Designing such complex devices requires ever more powerful multi-layered simulators. We propose to develop the next generation of photonic modeling tools based on a new graphical hierarchical circuit level software tool. This tool will bala ...

The objective of this project is to commercialize the Dual Band Extended Depth of Field Telescope System that is an innovative optical detection and imaging system that allows battlefield imaging through smoke, dust and fog obscurants in the 10 micron wavelength range. The system employs a dual band, multi-mode, diffraction-limited, infrared and visible telescope that can operate either in a passi ...

There is a need for a low profile, simple, accurate, localized, responsive sensor to measure shear stress in fluid flow. The unusual properties of shape memory alloys, and of Ni2MnGa in particular, suggest they could be sensing elements for shear. In recent years, single crystal films of Ni2MnGa have been grown by Molecular Beam Epitaxy (MBE). Once released from their substrate, these films hav ...

High power semiconductor lasers emitting around 2.3 microns have many military and commercial applications. Particulary interesting is the potential use of these devices as pump sources for optically pumped semiconductor lasers emitting in the 3-5 micron range. Having successfully developed the world's first high power 2.3 micron laser arrays in Phase I of this STTR, we seek to improve on the out ...

Advanced Acoustic Concepts, Inc. (AAC) proposes to extend its Phase I work in Auditory Cortex based sound classification. During Phase I AAC demonstrated the feasibility and accuracy of a computational model of human auditory processing based upon this cortical theory. AAC also demonstrated the concept by collecting a large number speech sounds and bird calls of various species and appling the cor ...
