This program will utilize in-situ monitoring devices during the HVPE growth of GaN in conjunction with thermal and gas flow modeling, to establish tighter tolerances over growth variables such as substrate temperature and growth rate, which will lead to more robust, producible HVPE GaN growth processes, and in turn increase large area wafer yield and boule thicknesses. The in-situ monitoring dev ...

SET, Inc. proposes to develop lattice-matched AlInN/GaN HFET structure on free-standing GaN substrate. By employing native low-defect GaN substrates and by using lattice-matched heterostructures with the incorporation of indium, we expect dramatic enhancement of these HFET in power density, reliability and high frequency operation. Homoepitaxial growth on native substrate and the use of AlInN/GaN ...

Due to their vast diversity and as-yet uncultivated status, detecting, characterizing and quantifying microorganisms in natural settings are of grand challenge, and understanding the mechanistic linkages between microbial diversity and ecosystem functioning and their feedback responses to human activities and climate change is even more difficult. There is an urgent need to develop rapid high thro ...

The interactions among different microbial populations in a community play critical roles in determining ecosystem functioning but very little is known about the network interactions in a microbial community due to the lack of appropriate experimental data and computational analytic tools. High-throughput metagenomics technologies can rapidly produce massive data, but one of the greatest challenge ...

The objective of this proposal is to demonstrate the feasibility of growing centimeter-size aluminum nitride (AlN) crystals by subliming polycrystalline AlN in nitrogen atmosphere, and to demonstrate single crystalline quality meeting or exceeding thestandards of commercially available SiC wafers. The growth process, which utilizes high temperature, subatmospheric pressure and a steep temperature ...

Kigre has an idea and evidence for a new family of broadband glasses that break all of Zachariasen's standard accepted rules for glass formation. This family of glasses is based upon the extensive use of multiple glass formers such as SiO2, B2O3, La2O3and P2O5. By employing multiple glass formers in a laser glass, Kigre is able to expand the bandwidth without sacrificing cross section and gain. ...

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 ...
