Cermet, in collaboration with researchers at Georgia Institute of Technology, proposes to implement a lattice matched III-Nitride technology using existing substrates. The implementation of a lattice matched substrate promises to produce near dislocationfree III-Nitrides for the first time while the use of an existing substrate technology dramatically lowers development cost and reduces the devel ...

Implant Sciences Corporation proposes to develop a superior power transistor design based on ion implanted nitride semiconductor materials which will be produced at Howard University. Our lateral device design features an inverted GaN channel with the AlGaN charge supply layer doped by ion implantation. Ion implantation allows selective area doping, which will let us create for the first time an u ...

Three-dimensional printed preforms will be used as mold patterns for MMCC's high-density, pressure resistant, castable refractory. Hard tooling will be eliminated from the Advanced Pressure Infiltration Casting process (APIC ). Cost for Al/Sic electronic housings will be slashed 75% over conventional pressure casting. Complex parts will be easily manufactured. Design modifications can be quickly i ...

The goal of the SBIR Phase I proposal is an attempt to grow the world's first single crystalline new wide band gap nitride semiconductors by MOCVD for developing optoelectronic and optical devices in yellow to green visible band as well as lattice matched heterostructure wide band gap electronic devices. The expected direct transition, wide band gap electronic structure and the significant nonline ...

Silicon has long been the semiconductor of choice for high-voltage power electronic applications. Recently, SiC has attracted attention because SiC is projected to have better performance than silicon. [1] SiC power switching devices have yet to becommercialized, largely due to SiC crystal defects, most notably the device-killing micropipe defect, which does not permit high total current parts t ...

It is proposed to develop, model, and demonstrate composite case materials with sympathetic responses to slow cookoff. In phase II, the proposed study will focus upon conducting subscale SCO testing on composite case materials and validate a physics based modeling and simulation tool. Subscale motor case dimensions will be analogue to a specific MDA rocket booster.
