A collaboration between Amethyst Research Inc., University Multispectral Laboratories (a government-owned, contractor-operated nonprofit corporation), and Teledyne Imaging Systems (a large defense contractor) proposes to develop/improve high-performance infrared sensors based on Type II, strained-layer superlattices (SLS). Such sensors offer (theoretical) advantages over state-of-the-art HgCdTe p ...

In Phase I we demonstrated a novel in-situ cleaning technique based on UV-activated surface reactions involving ozone and hydrogen to remove organic adsorbates and chemically-bonded impurities, e.g oxides, from the substrate surface. In Phase II the program will develop this process to significantly decrease the density of material defects in large-format, infrared, focal-plane arrays. Electrica ...

Accelerators used for nuclear-physics research require megawatts of radio-frequency energy. They currently employ vacuum-tube power amplifiers or conventional solid-state amplifiers that are inefficient and therefore consume a great deal of prime power. Many other applications including semiconductor processing, cellular-telephone base station transmitters and military communication systems simila ...

Conventional indoor environmental monitoring technologies are expensive, cumbersome to install and maintain, and do not provide the distributed granularity required to capture the necessary details for efficient energy management of commercial buildings. Developments in wireless sensor networks (WSN) provide substantial framework for monitoring and addressing indoor environments at scale. However ...

The objective of lab-on-chip (LOC) is to integrate and perform multiple analytical processes on a microchip platform. So far, most LOC research has been focused on electrophoretic separations. Limited progress has been made on multi-process integration, due mainly to the lack of a robust and miniaturized pump that can deliver constant flow and be integrated with LOC devices. Microchip HPLC can and ...

This Small Business Innovation research Phase I proposes the development of a practical and reliable in-vitro test for detecting the evidence of Mycobacterium tuberculosis (MTB) infection as an alternative to the tuberculin skin test (PPD-TST) and to the interferon gamma release assays (IGRAs). The proposed methodology will be a powerful detection technology in clinical diagnosis owing to its dete ...

Improved performance SWIR sensors with extended wavelength response to 2.5 microns will be developed using two disruptive technologies with which Amethyst has demonstrated success: nBn detector structures and defect passivation via hydrogenation. Similar to conventional extended wavelength photodiodes, the improved sensors will based on mismatched InGaAs grown on graded buffer layers on InP substr ...

ABSTRACT: A need exists for a reliable, low cost radiation-hardened, non-volatile (NV) memory in aerospace and defense applications and in reliable, long-life, high-speed NV memory for terrestrial and commercial applications. Present offerings can accomplish the objective, but only at the expense of performance, power, size, and weight. Recent refocus on magnetic memory technologies, stemming f ...

ABSTRACT: A need exists for a reliable, low cost radiation-hardened digital memory in aerospace and defense applications and in long-life, high-speed memory for terrestrial and commercial applications. Present offerings can accomplish the objective, but only at the expense of performance, power, size, and weight with device redundancy and shielding. Recent focus on Graphene and its capabilities ...
