The goal of this program is to develop a low cost, flexible manufacturing method for the production of high temperature ceramic composites for rocket propulsion systems. The matrix materials selected for this program will be ZrC, HfC, and TaC. These-materials have good oxidation/corrosion and ablation resistance at elevated temperatures, but typically do not possess the thermal shock resistance an ...

In the proposed research we will investigate methods for improving the performance of very long wavelength infrared (VLWIR) photovoltaic detectors fabricated from Hg1-xMnxTe. This material was chosen because Hg1-xMnxTe has been shown to have superior mechanical, chemical and thermal stability compared Hg1-xCdxTe. During previously SBIR-BMDO funded work, Brimrose Corporation successfully fabricate ...

Brimrose Corporation has developed a novel low-temperature and low energy ion-beam assisted growth process for minimizing the problems and improving the quality of the hetero epitaxial films of III-V compound semiconductors on foreign substrates such as silicon, germanium, etc. The improvement in the quality of hetero epitaxial InP/Si films will be achieved by using this novel low temperature grow ...

Phase I technical objectives of Brimrose Corporation are two fold. They are: 1) Epitaxial growth of AlxGa1-xN solar blind detector material device structure on new lattice and thermal matched substrates and evaluation of the material properties. The film growth will be carried out in Brimrose Corporation's 'Novel' ECR MOMBE Reactor using rare earth permanent magnets; 2) Preliminary epitaxial growt ...

CST proposes research and development of an artificial neural geometric engine designed according to a Lie group model of cortical visual information processing that can rapidly determine affine difference between two images. Computing parameters of geometric transform, such as scale, rotation, shear, shift, are considered as "inverse problem" in computer vision. The currently available warping an ...

Future spacecraft will require efficient heat transport at 60K Or lower, and will require flexible and thermal diode features. Cryogenic flexible heat pipes and capillary pumped loops have been developed, but are not capable of adverse tilt operation and rapid, autonomous startup. Loop heat pipes with advanced fine pore evaporator wicks show promise for meeting future needs, provided that rapid, a ...

Epitaxial Technologies proposes to develop innovative material structures for Auger transistors that can be used for millimeterwave oscillators. We will achieve this objective by performing device designs to determine suitable material structures and epitaxial growth processes. The primary goal of this proposed Phase I effort is to demonstrate the feasibility of Auger transistors by developing te ...

Epitaxial Technologies proposes to develop novel material and device tech, nologies using antimony-based active channels for highly linear microwave devices that can be used to simultaneously produce low noise and high power. To do this, we will perform materials and device design to determine suitable material structures and epitaxial growth processes. The main goal of this proposed Phase I effo ...
