The need for compact solid state ultraviolet light sources includes clinical light sources for a variety of surgeries, analytical instrumentation sources and communications systems based on shorter wavelengths that will be able to handle higher information densities. Such advanced optoelectric applications demand totally new materials. Of those available, silicon carbide is the most promising for ...

Commercially viable silicon carbide device manufacturing processes depend on an ability to grow'low defect density epitaxial layers. Low defect density epitaxial layers start with pristine SiC substrate surfaces. Epi-ready pristine SiC surfaces are not commercially available. The results of this-programme should remedy this. In Phase I we will demonstrate a cost-effective, reproducible ex-situ sur ...

BMD0 is interested in developing new electrical power system technologies that provide lighter, smaller, lower cost, more efficient and reliable power supplies for a variety of mobile or transportable systems, such as the proposed Ground Based Radar (GBR). Conventional power generation equipment technology will not be adquate to meet the size, weight and efficiency goals of these new systems. Cryo ...

Thermal Management has become the limiting factor in the advancement of many electronic systems. Current thermal management materials have either reached their performance limits or are impractical due to high costs. As applications for high density, high clock rate electronics increase, new cooling techniques and materials are required to allow low cost, high reliability operation. Technology ...

SURVEILLANCE IN THE INFRA-RED PART OF THE ELECTROMAGNETIC SPECTRUM DEMANDS INNOVATIVE CONCEPTS TO DESIGN QUANTUM WELL (QW) DETECTORS FOR WAVELENGTH BEYOND 12 UM. THE REQUIREMENT FOR LOW TUNNELING CURRENT AND SUPERIOR TRANSPORT PROPERTIES MAKE InAs-In(x)Ga(1-x)Sb, A TYPE II SUPERLATTICE, A SUITABLE CANDIDATE FOR INFRA-RED APPLICATION. STRAIN INDUCED BAND GAP VARIATION AND WAVELENGTH CONTROLLABILITY ...

Conventional shielding techniques for an electromagnetic pulse use high permeability magnetic materials. Such materials have limited effectiveness once they are saturated. A new approach for shielding has been identified using a layered film structure where the shielding actually increases after the magnetic film saturates. These results are based on the use of a new computer code which predicts ...

There are many military, commercial, and medical applications for a small, rugged, and inexpensive infrared (IR) spectrometer. A Fourier Transform Infrared (FT-IR) spectrometer would be an ideal tool for such measurements; however, FT-IR spectrometers are very sensitive to vibration and subject to misalignment from mechanically or thermally induced forces. To help overcome these barriers, BMDO pro ...
