The recent performance increases in graphics processing units (GPUs) have made graphics cards an attractive platform for implementing computationally intense applications. With their numerous parallel computational pipelines and SIMD architecture, modern GPUs can outperform high-end microprocessors by one to three orders of magnitude, depending on the problem. Most work to date at EM Photonics a ...

In this NASA SBIR Phase I proposal we propose to apply a highly conformal coating of ZnO and AlN or a double layer of GaN to the surface and internal pore walls of conventional microchannel plates (MCP). This will lead to enhanced secondary electron emission (SEE) and, thus, improve MCP gain for UV /X-ray detectors. The ZnO/ALN(GaN) hetrostructure using nano ZnO needles as templates has been demon ...

ABI's innovation is a novel centrifugal pump, which will not have bearings, shaft, and seals. The impeller in this pump would rotate in a stable position in the center of the pump housing. The balance of all hydodynamic forces acting on impeller achieves stability. This pump will have high reliability, durability, and low cost in reduced mass, power and volume configuration, which are required in ...

Reduced mass materials are critical to the success of aerospace systems. Thus, large air and space structures can benefit from lightweight composite materials. However, their adoption is impaired by the lack of a robust, cost-effective fabrication process, principally because the autoclaves used to consolidate composite laminates are so expensive for large parts. This program develops for US aeros ...

This Phase I program addresses the need for solar cells with greater than 30% efficiency for use as power sources for satellite systems operating in air mass zero (AM0) solar radiation. SVT Associates proposes to meet this need by developing a tandem cell composed of InGaAsN (1eV), GaAs (1.4 eV) and InGaP (1.85 eV) lattice matched to GaAs substrates. A projected efficiency of 38% would be obtained ...

This proposed Phase II program seeks to create dual-band pixel-collocated MWIR/LWIR photodetector arrays based on III-V semiconductor materials in a Type-II superlattice structure. The Type-II superlattice offers a customizable cutoff wavelength while maintaining a lattice-matched condition to the host substrate. This superlattice also has lower Auger-recombination, which reduces dark current no ...

High quality GaN epitaxial films are key to current efforts for development of both high-power/high-speed electronic devices and optoelectronic devices. In fact, solid state lighting, high-temperature and high-power electronics, microelectronic and mechanical sensors, and high-efficiency solar cells are all poised at a new level of development. This enormous market is waiting for low-cost, high ...
