WE PROPOSE TO DEVELOP A TOTALLY INTEGRATED MONOLITHIC GaAs/HgCdTe FPAs ON GaAs SUBSTRATED. THE INNOVATIVE FEATURES ARE: 1. THE DETECTOR IS FABRICATED DIRECTLY ON THE GaAs MULTIPLEXER SUBSTRATE, WITH THE MONOLITHIC METAL INTERCONNECT INSTEAD OF STANDARD INDIUM BUMPS ALLOWING ARRAY SIZES UP TO 1024x1024 WITH HIGH FRAME RATES. 2. THE FOCAL PLANES WILL INCORPORATE AN ON-CHIP LOW POWER MASSIVELY PARALL ...

Not Available In distributed command and control applications, video can provide significant help in terms of interpersonal communications, intelligence gathering, resource management, and other military functions. However, the available bandwidth is very limited in battlefield that necessitates the use of video compression. Current standards such as MPEG-1 (Motion Pictures Experts Group) can onl ...

There are no commercial amplifiers that can operate at temperatures above 125 degrees Celsius. We will combine two comparable wide bandgap semiconducting materials to make electronic amplifiers and switches that operate at high temperatures (at least 500 degrees Celsius). These devices can be controlled remotely by a light beam. Hence wireless coupling to a room temperature macroprocessor is possi ...

THIS PROJECT PROPOSES TO EXPLORE THE USE OF A WIDE BANDGAP SEMICONDUCTOR TO MAKE DEVICES CAPABLE OF OPERATING AT TEMPERATURES OF AT LEAST 500 0C. PN JUNCTIONS WILL BW FABRICATED. THE MAJOR THRUST WILL BE THE STUDY OF ELECTRODE TECHNOLOGY TO MAKE OHMIC CONTACTS THAT ARE STABLE AT HIGH TEMPERATURE AND IN THE PRESENCE OF AN ELECTRIC BIAS. THE APPROPRIATE METALLIZATION MUST RESIST BOTH THERMAL DIFFUSI ...

WE PROPOSE TO DEVELOP AND STUDY A NEW MANUFACTURING TECHNOLOGY FOR THE EPITAXIAL GROWTH OF MULTILAYERS OF III-NITRIDES SEMICONDUCTORS (GaN AND AlGaN) AT TEMPERATURES SUBSTANTIALLY LOWER THAN PRESENTLY ACHIEVED. THE TECHNIQUE IS BASED ON THE ION BEAM DEPOSITION SYSTEM WHERE THE IONS ARE GENERATED BY AN ELECTRON CYCLOTRON RESONANCE (ECR) MICROWAVE PLASMA. THE ENERGY OF THE IONS INCIDENT ON THE SUBST ...

THE PROPOSED RESEARCH AND DEVELOPMENT EFFORT WILL EXPLORE THE ELECTROLUMINESCENCE PROPERTIES OF RARE EARTH ELEMENTS IN A III-V SEMICONDUCTOR. THE TECHNIQUE OF IMPACT EXCITATION, CURRENTLY USED IN COMMERCIALLY AVAILABLE ELECTROLUMINESCENCE DISPLAY DEVICES, WILL BE STUDIED FOR EXCITING THE RARE EARTHS. WE HAVE ALREADY DEMONSTRATED THE POSSIBILITY OF GENERATING VISIBLE LIGHT BY HOT ELECTRON IMPACT EX ...
