In this STTR program, Structured Materials Industries, Inc. (SMI) and our partners are developing commercially viable fabrication technology for oxide heterostructure based nanoelectronic devices. Oxide heterostructures, consisting of a polar oxide such as LaAlO3 and a non-polar oxide such as SrTiO3, offer a novel route to building nanoelectronic devices. The benefits of these devices will inclu ...

We propose to demonstrate and advance several key aspects of our novel, scalable ammonothermal technology for growth of high quality single crystal gallium nitride. Specifically, we propose to demonstrate a high growth rate and high crystalline quality, to design and analyze a pilot-scale reactor, and to construct and validate a quantitative model to describe the fluid dynamics of the growth envi ...

Nanoscale infrared detectors are emerging as a potentially powerful alternative to traditional infrared detector technologies. The University of New Mexico has developed dots in a double well (DDWELL) quantum dot infrared photodetectors which have a spectral responsivity that can be tuned by controlling the bias voltage applied. In this Phase II effort, Polaris Sensor and UNM would fabricate a g ...

We intend to use the emerging technology of compressed sensing and related new algorithms of information science to (1)increase our capacity for hyperspectral image acquisition beyond current capacity by developing new imaging and spectroscopic systems,(2) expand the frontiers from signal recovery to new applications, emphasizing knowledge learning including target and anamoly detection, and (3)st ...

The objective of this project is to develop a practical finite element-based simulation of spin-pit tests of disks. The performance of disks in spin-pit tests critically depends on localized effects, such as residual stresses, dislocations, and microstructure gradients. Therefore, a two-scale modeling approach is adopted. At the global-scale, the disk is represented by means of finite elements wit ...

The design of future hypersonic vehicles requires detailed understanding of flow regimes ranging from rarefied to continuum. Hypervelocity flows are characterized by high temperatures, real gas effects, nonequilibrium chemistry, and ionization. The goal of this project is to develop unified kinetic/continuum solution methods with automatic domain decomposition for a wide range of Air Force applic ...

Our team proposes to develop, test, and commercialize a Micro Air Vehicle Tether Recovery APparatus (MAVTRAP). This system operates by deploying an instrumented MAV capture device attached via a tether system from a mothership unmanned air vehicle (UAV). The instrumented MAV capture device contains an integrated avionics suite. Our team will determine and control the precise mother ship UAV loi ...

Radiative heat transfer is a dominant mode of heat transfer in combustion and propulsion systems as well as for hypersonic flow encountered during planetary entry. Solution of the Radiative Transfer Equation (RTE), which is an integro-differential equation, places stringent requirements on the computational resources as: (a) the radiation depends both on spatial and angular dimensions, (b) radiati ...

The gap between research in numerical methods and popular commercial solvers in CFD and related areas has been gradually widening in the recent past, particularly in the realm of high order accurate algorithms. At HyPerComp we are advancing a suite of high order codes based on the discontinuous Galerkin (DG) technique that can be used in electromagnetics, fluid mechanics, MHD and radiative heat tr ...

Aurora and Georgia Tech’s Phase I efforts demonstrated the feasibility of a partially distributed control scheme with separate controllers on the engine core and fan, where the controllers are linked by a supervisory controller. This scheme is representative of the situation encountered in VTOL UAV design and the design of new turbo-props and variable pitch turbofans by the large commercial gas ...
