Active Control eXperts, (ACX) Inc. proposes to design, fabricate, and demonstrate a novel hybrid vibration ccntrol actuator system capable of very precise, controllable motion. This system will combine the advantages of a capacitive actuator with feedback control capability. This system will possess the force and stroke characteristics of a small hydraulic device and the bandwidth of electric moto ...

The superior optical properties of BBO and its applicability in frequency doublers and waveguides justifies development of thin film deposition processes which can be integrated with microelectronic processing. The high damage threshold of BBO, a necessary component for device integrity, is a major advantage over other nonlinear optic materials. In Phase I, chemical precursors and a deposition pro ...

We propose to demonstrate the feasibility of solar-blind, multi-spectral III-V nitride UV detectors which can meet the requirements of applications in both the military and commercial sectors (missile threat warning, UV search and track, environmental monitoring in gas turbines, and general flame detection). A novel aspect of our approach is the use of SiC as a substrate for these devices, which w ...

Phase I will develop a gas-phase process for the deposition of low dielectric constant polymers for use in integrated circuits. This process will utilize the firm's liquid delivery technology to deliver the reactants and grow films at high deposition rates. Polymerization will be induced by thermal activation on a heated substrate. This novel approach to polymeric film growth enables the depositio ...

Radiation hardened ferroelectric random access memory (FRAM) devices have potential uses in numerous military applications. Until recently, FRAMs have relied on lead zirconate titanate (PZT) as the storage material. However, a new class of materials promises to offer higher device reliability and easier integration into existing technologies. SrBi2Ta209 has been identified as a material of choice ...

Silicon carbide (SiC) is an ideal semiconductor material for high temperature, high frequency, and high power electronic devices. A SiC technology analogous to silicon - on -insulator (SOI) will be feasible if a suitable dopant precursor and epitaxial growth technique to produce semi-insulating SiC can be developed. Vanadium is an attractive dopant for the formation of semi-insulating SiC. In Phas ...

Metal-ferroelectric-semiconductor field effect transistors (MFS-FETs) have a can be used as nonvolatile memory devices. The primary ferroelectric materials for these devices are perovskite oxides such as lead zirconium titanate (PZT) and strontium bismuth tantalate (SBT). These materials contain highly mobile elements (Pb and Bi) that can interact with silicon at process temperatures and lead to a ...

This Phase I project will develop certain innovations in silicon wafer micromachining, and pulsed-laser deposition, to fabricate arrays of pyroelectric detectors from epitaxial metal-oxide thin films. These pyroelectric materials will be ferroelectric metal-oxides and hence have very large electric polarizations. Epitaxial films ensure low dielectric noise, and allow photolithographic array patter ...

X-ray imaging is an important technique which is used in variety of applications such as general radiology in medicine, astronomical observations, non-destructive testing, X-ray diffraction for materials studies and others. The ability of X-rays to penetrate deep in to matter allows investigation of interior components with possibility of real-time dynamic studies. However, while significant advan ...

This Small Business Innovation Research Phase l project is proposed by American Superconductor Corporation (ASC) to establish the feasibility of hermetically manufacturing small-filament, high temperature superconducting (HTS) composite wires for use above 20 K in AC magnet applications such as inductive energy storage devices. HTS magnet wire applications will typically operate under fluctuating ...
