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 ...

Currently, thermal spray (flame and plasma spray) is the only single step method of applying most metal and non-oxide ceramic coatings to large objects. These coatings are usually of a low quality, and thin films cannot be applied. An in situ deposition technique that inexpensively and easily applies nitrides, carbides and other non-oxide thin or thick films in an environmentally friendly manner i ...

Currently vacuum based methods of PVD and CVD are the only processes for forming GaN thin films and coatings. These methods are usually expensive and are not applied in a production friendly manner. An atmospheric deposition technique that inexpensively and easily applies GaN thin or thick films in an environmentally friendly manner is a priority for any number of DOD and commercial applications. ...

A THEORETICAL PROGRAM IS PROPOSED TO INVESTIGATE A COMPACT, LOW-VOLTAGE INFRARED GRATING LASER WITH MULTI-KILOWATT OUPUT CAPABILITY. THE RADIATION IS GENERATED BY THE PASSAGE OF AN ANNULAR BEAM OF ELECTRONS THROUGH A COAXIAL PAIR OF CONDUCTORS, THE INNER CONDUCTOR BEING A CORRUGATED CYLINDER WHICH FORMS THE GRATING. THE ELECTRON BEAM IS GUIDED BY AN AXIAL MAGNETIC FIELD. THE DIMENSIONS OF THE OPTI ...

The primary goal of Phase I work is to demonstrate the feasibility of synthesizing gallium nitride (GaN) powder. Secondarily, this powder will be used to grow high-purity single crystals of GaN from a liquid GaN phase. This would be accomplished using a proprietary variation of the skull melting technique. Since GaN demonstrates peritectic-type decomposition at atmospheric pressure, the entire sku ...

This proposal suggests that a basic data collection, management, and fusion framework is ideally suited for integrating distributed data from multiple heterogeneous sources and making it available on a multi-point basis for analysis, viewing, and C**4I applications. The basic framework proposed was built (and is currently under ongoing development) to support object-oriented, temporally consistent ...

This program will demonstrate key enabling technologies for Terabit/second optical fiber networks capable of meeting critical DoD needs. Optical network technology offers characteristics that satisfy many DoD requirements. These characteristics include improved data handling through multiwavelength transmission in single optical fibers; enhanced network security; greater inter-network operabilit ...

MANY CURRENT AND PLANNED DEFENSE AEROSPACE PROGRAMS DEPEND CRITICALLY UPON RAPID DEVELOPMENT OF LIGHTWEIGHT COMPOSITE MATERIALS HAVING UNPRECEDENTED HIGH-TEMPERATURE PROPERTIES. CONTINUOUS FIBER REINFORCED INTERMETALLIC MATRIX COMPOSITES (IMC'S) HAVE THE POTENTIAL TO MEET THESE PERFORMANCE REQUIREMENTS, AND CONSIDERABLE RESEARCH EFFORT IS NOW DEVOTED TO DEVELOPING THEM. WE RECENTLY DEMONSTRATED A ...
