GaInSb/InAs superlattices show great promise as materials for use in very long wavelength infrared (VLWIR) detectors. This III-V compound offers advantages over current HgCdTe technology in both anticipated performance level and ancillary support system(e.g. cryogenic cooling) costs. Due to its piezoelectric characteristic, (111)-oriented superlattice lowers the effective bandgap energy when com ...

This Small Business Innovation Research Phase I project proposes a new detector material for single mode optical fiber communication over the information highway. High performance detectors are an enabling technology for the moderate to long distanceoptical transmissions at 1300 and 1550 nm wavelengths. However, due to material related problems, detector devices are not yet practical for such opt ...

AlInGaN-based heterostructures have demonstrated unmatched versatility in optical and electronic applications. In particular, AlGaN/GaN high electron mobility transistors (HEMTs) are the leading candidates for realizing ultra-high frequency, low-noiseand high-power amplifiers. The addition of indium to the composition of these HEMTs is expected to dramatically improve their performance. We prop ...

Fiber optical transmission is increasingly applied to computer network, secure telecommunication systems, military aircraft, and even in missile guidance systems. 1300 nm vertical cavity surface-emitting lasers (VCSEL) are becoming a prefered technologyfor transceivers in short- and medium-haul, enterprise and metro data network. There is significant interest in using diluted nitride GaInNAs as ac ...

"The material Indium Gallium Arsenide Nitride (InGaAsN) is a novel compound semiconductor ideally suited for infrared optical devices. This material may be grown on GaAs substrates and can take advantage of mature GaAs processing technology. Quantum dots,a subset of the nanotechnology field, are structures whose physical dimensions are in the range of 10 nanometers, a size on the order of indivi ...

InAs/GaInSb type II superlattices show great promise for use in Very Very Long Wavelength Infrared (VVLWIR, for wavelength > 20 um) detectors. System analysis indicates early detection of space borne vehicles is more easily achieved in this infraredregime. This III-V compound compares very favorably with the current HgCdTe technology in anticipated performance, manufacturability and operating cos ...

High power AlGa-nitride RF electronics are of great interest to various DoD applications. This proposal will utilize an advanced plasma deposition process to passivate surface traps on the devices, to dramatically reduce surface-related transient effectsand improve the device performance. We will use this technique to produce high quality passivation layers, such that charge traps in the layer can ...

SVT Associates proposes an enhanced GaN:Er light emitting diode fabricated on silicon substrate and can be integrated with thin film waveguide, such that light propagation can be manipulated for fast on-chip or chip-to-chip interconnect. A key component ofthe optical communication on a chip is an efficient light source. Since the efficiency of electron impact-induced luminesence of Er is high, it ...

This Small Business Innovation Research (SBIR) Phase I project is directed toward the development of highly sensitive, solid-state, solar-blind photodiodes based on the group III-nitride material system, aluminum gallium nitride. Ultraviolet detectors are used in water treatment plants, automated arc-welding systems, and the monitoring of atmospheric ozone depletion. The objective of the proposed ...
