Silicon carbide materials will revolutionize semiconductor devices for military and commercial markets. The material's wide bandgap, high electric field breakdown, high thermal conductivity give SiC capabilities that far exceed those of silicon or gallium arsenide. Despite significant progress in silicon carbide development, fundamental defects--most prominently micropipes--persist. If SiC is to s ...

The properties of single-crystal silicon carbide are such that electronics devices from this material have demonstrated remarkable performance characteristics. Despite the material's promise, the material has not yet found acceptance in mainstream device markets because of the material's high cost, among other reasons. This Phase I SBIR proposes an SiC source powder with unique properties which wi ...

A novel technological approach was recently devised by Sumi Tech engineers to fabricate multilayer electronic components, which enables the manufacture of devices with very high volumetric efficiency and reliability. Inexpensive electrode materials such as copper, or aluminum are potential candidates, since the process takes place at relatively low ambient temperature (e.g., less than 400 C), thus ...

One highly desired improvement for neutron sensing is an imaging neutron detector with high two-dimensional spatial resolution and a large detector area. At present, achievable real-time neutron imaging detector resolution is only about 1 mm. The innovation proposed is to adapt for neutron imaging the high spatial resolution Microchannel Plate (MCP) detector technology so widely used for detecting ...

The III-V nitride semiconductor family affords many unique properties which make these materials attractive candidates for producing electronic and optoelectronic devices. Much progress has been made in epitaxial thin film growth of nitrides using metalorganic chemical vapor deposition (MOCVD) and molecular beam epitaxy (MBE) during the last decade. These efforts are hindered by the lack of lattic ...

CoreTek Inc proposes a rewritable ferroelectric thin film disk drive (Ferro-Disk), which is addressed optically and read out electronically. The Ferro-Disk stores data in the form of electric remnant polarization in a ferroelectric film. Because ferroelectric materials are radiation hardened, the Ferro-Disk is specially suitable for reliable data storage during space missions. The architecture a F ...

CoreTek, Inc. proposes a novel integrated tunable diode laser for Military and Commercial applications. In our proposed approach broad tuning (50-1OOnm) is achieved via on-chip integration of a novel electro-optic thin film waveguide with semiconductor laser diodes. The high electro-optical properties of the proposed thin films allows simultaneous broad tuning and extremely narrow linewidth (5Onm) ...

A compact, high power pulse UV laser would find many immediate applications in a variety of fields including bio-sensing. high-density data storage, printing, photolithography, remote sensing and detection of explosive materials. In response to this need, CoreTek, Inc. proposes to develop and commercialize a compact, diode-pumped, micro-cavity UV laser to generate an optical pulse train of sub-nan ...
