A COMPUTER CODE TO SIMULATE SHORT-WAVELENGTH (SINGLE-PARTICLEINTERACTION DOMAIN) FREE ELECTRON LASER (FELS), INCLUDING ALL THE IMPORTANT PROPERTIES OF THEIR INTERACTIONS WITH UNSTABLE OPTICAL RESONATORS, WILL BE DEVELOPED. THIS CODE WILL BE APPLIED TO A NOVEL CLASS OF UNSTABLE RESONATOR THAT HAS A COMPACT OUTPUT BEAM. THIS CLASS OF UNSTABLE RESONATOR IS ESPECIALLY WELL ADAPTED TO THE FEL BECAUSE, ...

A STUDY OF THE EFFICIENCIES AND ENGINEERING TRADE-OFFS INTEGRATING REDUNDANT NUMBER SYSTEM WITH SYSTOLIC ARRAY PROCESSING ELEMENTS IN ORDER TO CAPTURE THE INHERENT FAULT TOLERANT PROPERTIES OF SIGNED DIGITS IS PROPOSED. USING SIGNED DIGITS REDUCES CARRY/BORROW DISTANCE TO A MINIMUM THUS REALIZING HIGHLY MODULARIZED AND COLUMNAR ARITHMETIC ENGINES. PROCESSING CELLS BECOME REGULAR WITH FEWER INTERCO ...

WE PROPOSE TO APPLY A BIOTECHNOLOGY-BASED PROCESS TO MAKE NANOSTRUCTURES FOR OPTOELECTRONIC APPLICATIONS. THE RESULT WILL BE A UNIFORM ARRAY OF SILICON QUANTUM BOXES OF IDENTICAL DIMENSIONS IN A SILICON LAYER OF CONTROLLED THICKNESS. ALL THREE TECHNIQUES, CONTROLLED THICKNESS OF A CRYSTALLINE Si LAYER, FORMATION OF A UNIFORM ARRAY, AND ITS USE AS A PATTERN FOR REPLICATING A SEMICONDUCTOR ARRAY, HA ...

The proposed project will produce single-crystal boules of GaN that can be sliced and sold as high-quality substrates for the epitaxial growth of differently-doped GaN or of other lattice-matching crystals, or as wafers for use in optoelectronic and acoustooptic applications. The feasibility of GaN boules will be tested on a small scale: to produce cm3-sized crystals. The process will be scles up ...

Astralux, Inc. will develolp a seminconductor sensor sensitive to bacuum ultraviolet photons. For this, we shall synthesize a wide bandgap semiconductor capable of forming a built-in electric field that will separate the photogenerated electron-hole pairs and produce a photovoltage in response to the incident UV. This sensor should have no response to light in the visible spectrum. In this project ...
