Adroit Systems, Inc. will develop a Pulse Detonation Synthesis (PDS) process to manufacture ceramic powders from gas-powder reactant mixtures more efficiently and inexpensively than current methods. A high combustion rate and simple design make the PDS system capable of mass producing these powders, which are used as raw materials for high-temperature, high-performance ceramics and ceramic composi ...

Functional gradient materials (FGMs) have a microstructurally graded transition in composition (e.g. zirconia to a nickel based superalloy). The graded transition eliminates problems associated with a discrete interface such as poor mechanical strength and transport losses. They are being actively pursued by the engineering community, particularly in Japan, as a means of taking advantage of two di ...

This Phase I project has two primary objectives. The first objective is to evaluate the feasibility of a fully ion implanted fabrication process based on the heterodimensional 2-D MESFET. The new device, the 2-D JFET, will have p+ ion implanted sidegates which laterally modulate a thin, highly doped n-type conducting channel. The 2-D JFET should have excellent high speed, low power characteristics ...

This Small Business Innovation Research Phase I program will determine the practicality of increasing the second harmonic (SH) output of frequency doubling devices by at least 5 times current gutput powers. Altos has demonstrated in preliminary experiments have a 2 times to 3 times increase in SH output by creating thermal gradients across the waveguide structures used to frequency double the lase ...

ASTROPOWER PROPOSES TO DEVELOP A NEW FRONT-ILLUMINATED, ALUMINUM GALLIUM PHOSPHIDE (AlGaP) BASED, CHARGE-COUPLED DEVICE (CCD), ULTRAVIOLET (UV) IMAGING ARRAY. THIS NOVEL ARRAY TECHNOLOGY HAS NEVER BEEN SUCCESSFULLY DEVELOPED. THREE NEW INNOVATIONS WILL BE NECESSARY TO ACOMPLISH THE AlGaP CCD. THESE ARE: AlGaP MATERIAL QUALITY WHICH CAN SUPPORT A CCD DEVICE; THE GROWTH OF A NATIVE OXIDE ON THE AlGa ...

The Phase I Project will develop a comprehensive model to evaluate and optimize state-of-the-art light-emitting diodes for optical memories, optical computing, and fiber or free-space photonic interconnects. The innovation is the development of resonant optical cavity LEDs and a proprietary low-cost epitaxy technology for their fabrication. A unified approach to the design of LEDs with resonant op ...

AstroPower proposes to develop a new high voltage solar cell for photovoltaic linear concentrator arrays based on our thin GaAs solar cell and epitaxial lateral overgrowth technologies and applying lateral segment interconnection techniques. This solar cell design has several advantages which make it ideal for space concentrator systems. These are high system voltage (10 to 500 volts per cell), re ...

We propose exploratory development of new epitaxial growth technologies for low-defect GiN epitaxial structures and surrogate substrates. A significant feature of our approach is epitaxial latval overgrowth for "defect filtering." We present arguments that such epitaxial lateral overgrowth will lead to GaN material of unprecedented quality with respect to defects, stress, and purity. In the Phase ...
