In this abstract the development of vertical power transistors utilizing bulk GaN substrates with breakdown voltages of 1200V or higher, normally-off operation, and a drain current rating of 100A is proposed. These devices will feature vertical current flow, avalanche ruggedness, and a wide operating temperature range (-55 to 150°C). The target specific on-resistance for the transistor is 30x low ...

In this program, we will develop a breakthrough technology that will enable wafer-scale epitaxial lift-off (ELO) of GaN power device heterostructures from low-dislocation-density bulk GaN substrates. This technology will be used to provide a low-cost vertical junction field effect transistors (VJFETs) with high breakdown voltage (greater than 1,200 V) and high current capability (greater than 100 ...

The team of Monolith Semiconductor, X-FAB Texas, Rensselaer, United Technologies and Univ. of Arkansas will provide breakthrough advances in switch performance and manufacturing cost reduction to deliver cost-effective 100Amp, 1200V SiC power MOSFETs to enable widespread adoption. Based on the combined expertise in both Silicon and SiC power device design and processing, Monolith Semiconductor is ...

Innovative Biotechnologies International, Inc., has reported previously a simple method to detect viable Cryptosporidium parvum oocysts in drinking water using the isothermic Nucleic Acid Sequence-Based Amplification (NASBA) method, coupled with a rapid liposome nanovesicle (Nanozome)-based biosensor technology. This assay system is based on the ability to immunocapture low numbers ...

Picarro, Inc., will build a trace gas sensor based on cavity ringdown spectroscopy (CRDS) targeting the acrolein absorption band at 1623 nm for environmental monitoring. Acrolein is a ubiquitous airborne pollutant. Its sources include burning vegetation (e.g., forest fires), waste incinerators, furnaces, fireplace, gasoline- and diesel-engine emissions, power plants, polyethylene ...

The sensitivity of low-cost, portable volatile organic compound (VOC) detectors currently in use is low, which limits their application in many situations. More sensitive detectors are more expensive and less robust and not suitable for field use. This Phase I project involves the development of a membrane-based preconcentrator able to concentrate trace amounts of VOC contaminants to levels that ...

Perchlorate is a widely used component of solid fuel, missile and rocket propellants, explosives, and pyrotechnics. It has been shown to reduce iodide uptake into the thyroid gland. The U.S. Environmental Protection Agency (EPA) has found perchlorate contamination in 18 states and believes contamination may exist in as many as 39 states. In early January 2005, the National Academy of Science ...

This Phase I SBIR project addresses environmental problems associated with indoor air quality (IAQ) and energy consumption in residential buildings. As building envelopes increasingly become tight to satisfy energy efficiency requirements, health conditions that are correlated with IAQ, such as asthma and allergic diseases, are on the rise. The most effective strategy to improve IAQ is ventilation ...

A large number of potentially harmful chemicals and pollutants in the environment make comprehensive experimental chemical testing cost prohibitive and unrealistic. Methods that can decrease the required experimental work and aid in the streamlining of this process would provide a valuable tool in this area. Computational cellular modeling can provide a significant improvement in linking expo ...

Lead in household paint and dust is a serious health hazard, as low-level lead exposure can result in a number of adverse health effects, especially in children. Onsite and real-time detection and quantification of lead in paint/dust are very important to homeowners and certified lead-based paint removal professionals. Toward this end, both field-portable equipment (such as X-ray fluorescenc ...
