This Small Business Technology Transfer Phase II Program will demonstrate a magnetic field sensor device of high sensitivity using spin-dependent tunnel (SDT) materials. The tunnel materials will be developed with guidance from the state of the art realistic atomistic modeling and aided by state of the art nanostructural characterization techniques of 3-D atom probe and high-resolution transmissio ...

The use of Net-Centric Enterprise Services (NCES) to provide ubiquitous access to information within the Department of Defense presents challenges in both the design and implementation of these systems. The need to provide information to the war-fighter in a timely manner while maintaining the security of the system in challenging environments far exceeds the capabilities of present day enterpris ...

A parallel random number generation suite that generates, dynamically, millions of parallel pseduorandom number streams suitable for consumption by high performance computing (HPC) applications on various platforms will be implemented, tested, and provided to Government, academic and private HPC users for their evaluation and use. The software will be tuned for scalability, repeatability and effic ...

This Phase I program is focused on enhancement of the performance of MgZnO based solar blind detectors. MgZnO alloys have superior optoelectronic properties with bandgaps suitable for solar blind detection. Issues related to doping and miscibility will be addressed. This will involve the use of advanced MOCVD and MBE growth techniques and consideration of both Schottky and p-n junction devices. No ...

This work seeks to develop the ultra-low-frequency performance of spin-dependent-tunneling magnetic-field sensors through the use of novel thin-film materials to lower the frequency-dependent excess noise and increase the signal response. What is proposed is an investigation of novel thin film materials recently discovered to have high magnetoresistance effects. Magnetic sensor devices will be f ...

A new Aluminum gallium nitride (AlGaN) based heterojunction field-effect transistor (HFET) structure is proposed that utilizes avalanche impact ionization for very high frequency operation (>100 GHz). The main goal of this program is to demonstrate the potential of these devices as a replacement for vacuum tubes in mm-wave applications including radars and communications transmitters. In the Pha ...

Two technologies with nearly perfect complementary capabilities are combined in this project. Univer-sity of Virginia has developed the Tactical Interface for Monitoring and Retargeting (TIMR), based on recent Tactical Tomahawk work. This provides decision aiding and an underlying simulation platform, but by design provides no autonomous planning capability. SIFT has developed PlaybookT, an int ...

We will address the requirement for fault identification and isolation in fiber optic data links by incorporating an optical time domain reflectance (OTDR) functionality into the transceiver module. Our approach is to monolithically integrate a high speed photodetector that will sense reflections from discontinuities in the optical channel, with the 850nm VCSEL which transmits the signal.
