SixPoint Materials will create low-cost, high-quality vertical gallium nitride (GaN) substrates using a multi-phase production approach that employs both hydride vapor phase epitaxy (HVPE) technology and ammonothermal growth techniques to lower costs and maintain crystal quality. Substrates are thin wafers of semiconducting material needed for power devices. In its two-phase project, SixPoint Mate ...

NanoSD, Inc. with its partners will develop a transparent, nanostructured thermally insulating film that can be applied to existing single-pane windows to reduce heat loss. To produce the nanostructured film, the team will create hollow ceramic or polymer nanobubbles and consolidate them into a dense lattice structure using heat and compression. Because it is mostly air, the resulting nanobubble s ...

As the U.S. Government increases participation in post-conflict Stabilization and Reconstruction Operations (SARO) around the globe, the ability to understand the relationships between task completion and mission completion is critical. The US Government employs a metrics tool developed though the Monitoring Progress in Conflict Environments project. The objective of this Phase II STTR is to provi ...

To meet the U.S. military needs for hardened laser-ranging sensors for munitions applications, a compact, high-repetition-rate, high-pulse-energy laser rangefinder will be developed consisting of a temperature-stabilized avalanche photodiode (APD) receiver, with a few photons equivalent sensitivity, and a miniature diode-pumped microchip laser. An existing integrated circuit design will be updated ...

This proposal addresses the problem of PCSS/laser trigger integration using a single monolithic laser diode array, thus simplifying the entire optical delivery network necessary for efficient operation of PCSSs. The proposal constitutes a logical continuation of Phase I effort where the main focus was on the detailed design of the PCSS/laser diode array (LDA) integrated architecture. In Phase II ...

Pulse voltammetry techniques, coupled with model-based analysis tools, provide a number of advantages for quantitative analysis of electrochemically active materials that govern the performance of batteries and fuel cells. In prior Phase I and II research, CFD Research developed and validated computational models in software that reads voltammogram data from laboratory instruments; predicts the re ...

The project will remove a key difficulty that currently hampers many existing methods for computing unsteady electromagnetic waves on unbounded regions. Numerical accuracy and/or stability may deteriorate over long times due to the treatment of artificial outer boundaries. We propose to develop a universal algorithm and software that will correct this problem by employing the Huygens' principle an ...

The area of thin film growth has progressed rapidly, producing many high performance new materials which require accuracy of their atomic composition to perform as expected. Any method to provide real time in situ information about the elemental composition of the growing surface is highly valuable for these new, complicated materials. Utilizing a new instrument design, the Phase I project team ...

An innovative and fundamental approach to measure far field noise of a helicopter using a hot-air balloon as an acoustic measurement platform is described. The technique, featuring a microphone suspended beneath the basket of a hot-air balloon, is used to obtain acoustic data above, in, and below the horizon plane of a helicopter in forward flight. This approach is postulated to have many advantag ...

Deposition of highly conductive, continuous thin film metals has proven to be a significant challenge. There are several techniques that allow deposition of these metals, but their application is limited to planar surfaces and only offer complete line of sight deposition. During a recent Phase I STTR project, Summit Information Solutions, Inc. (Summit), in partnership with University of Alabama in ...
