The development of a process to produce semi-insulating (SI) silicon carbide (SiC) boules with improved yields will significantly reduce the cost of wafers and thus accelerate the rapid commercialization of SI SiC for microwave and RF system applications.The objective of this Phase II project is to improve and perfect the process development of a radically new approach for the synthesis of high pu ...

We proposed a simple wafer scale method to leap frog current CMOS technology. The slow-down in CMOS scaling is limited by technology difficulties and by economics. In tooling up for .13-micron technology, the jump from .18-micron is costing $10 billionis equipment alone, plus accompanying expenses of redesign and module formulation. The net effect of this massive capital investment is to replac ...

60311 There are economic and environmental justifications for replacing conventional distillation processes with simpler membrane separations in certain applications. However, at present, there are no commercial membranes able to withstand the aggressive conditions associated with important industrial chemicals, including hydrogen fluoride, hydrogen chloride, and ozone. Prototype, chemic ...

60395 Emissions of volatile organic compounds (VOC) from gasoline refueling facilities continue to be an energy, safety, and environmental issue. In such applications, it is desired to vent the air in the system and keep the VOC behind. This project will develop a reverse separation membrane (RSM) system that allows for rapid venting of air while retaining the gasoline in underground storag ...

A nearly universal trend in modern technology is the continued integration of systems, and their associated devices, on decreasingly smaller scales. While this has led to personal computers that offer more functionality and faster computational speeds, ithas also spurred the development of hybrid optoelectronic systems on a chip (SOCs). Currently, such SOCs are receiving significant interest fro ...

The overall goal of the proposed research is to develop a comprehensive, efficient, and well validated model of various remelting processes used for the production of ingots of superalloys and titanium alloys. Phase I research has demonstrated thefeasibility and the validity of developing a unified computational model for efficient and accurate prediction of AC and DC electromagnetics, fluid flow, ...

Kigre's Phase I fiber amplifier development effort demonstrated 10dB of internal gain at 1.54um from 2.2 cm long section of MM-2 erbium ytterbium phosphate fiber amplifier pumped at 980nm. 26dB of gain was also produced from a 8.8com long section of thissame fiber pumped at 1480nm. Mode field image testing of a fiber show this MM-2 fiber to be perfect 1.54um single mode containment match to stan ...

A breakthrough in fiber laser technology has been achieved which opens the door to a whole class of efficient ultra-high brightness laser sources. These diode pumped devices have the potential to replace or augment almost all existing industrial, medical,and military laser applications. Kigre's new QX phosphate laser materials exhibit high strength, high gain, high durability and superior laser ...

This Small Business Innovation Research Phase II project,

Spin-dependent-tunneling (SDT) sensors are emerging as a microelectronics-based magnetic-sensor technology for the broadband detection of low-level fields produced by objects such as military or commercial vehicles. The sensors offer the potential of smallsize, low cost, low power, and low-field resolution. The sensitivity of the devices is high, however they exhibit a significant
