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 ...

There is a market for a room temperature infrared detector as well as for a detection system which is radiation resistant and works at high temperatures and in reactive environments. Current infrared imaging technologies are too expensive and too bulky for these applications. We are proposing to develop an infrared and thermal detector based on a novel kind of light converter. The concept incorpor ...

BRIMROSE CORPORATION PROPOSES TO INVESTIGATE, DESIGN AND DEMONSTRATE A NOVEL OPTICAL BISTABLE DEVICE WITH A THRESHOLD OPTICAL INTENSITY SEVERAL ORDERS OF MAGNITUDE LOWER THAN THE CONVENTIONAL DEVICES. THIS DEVICE WILL OPERATE AT ROOM TEMPERATURE USING A LOW POWER CW LASER. ADVANTAGE OF SUCH A DEVICE WILL SIGNIFICANTLY FACILITATE THE NUMBER OF PROCESSING OPERATIONS IN OPTICAL COMPUTING AND SIGNAL P ...

IR DETECTOR MATERIAL, MERCURY CADMIUM TELLURIDE HAS BEEN THE MOST MATURES AND OFTEN A MATERIAL OF CHOICE FOR ADVACNED INFRARED DETECTION. HOWEVER, IT IS EXTREMELY DIFFICULT TO PRODUCE THE MATERIAL FOR DETECTION AT A WAVELENGTH GREATER THAN 14um. THIS PROBLEM IS DUE TO EXCCESSIVE FUNNELLING AND SURFACE LEAKAGE RELATED TO DARK CURRENTS. IN RECENT YEARS MERCURY ZINC TELLURIDE (MZT) HAS EMERGED AS A S ...
