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 ...

Spatial light modulators (SLM's) have been identified as critical elements in many optical computing and signal processing applications. Typically these devices use expensive bulk ceramics that result in high cost and difficult device integration. Ceramic materials in the PbLaZrTiO3 (PLZT) family of compounds show a unique combination of high transparency, large electrooptic effects and exceptio ...

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 ...

UV diode detector arrays have a wide range of both commercial and military applications. Examples include spectral measurement and calibration, pollution monitoring, environmental change monitoring, remote sensing of earth resources, solar UV monitoring, burner monitoring in gas turbines, flame detection in furnaces and for fire detections, etc. SiC is one of the most promising material for UV di ...

New applications of acoustical microscopy, performed at frequencies above 200 MHminiature transducer geometries to enable in vivo applications and to enhance present in vitro capabtechniques will be used to create piezoceramic transducer elements with novel geometries. In Phase It ...

Next generation power electronic systems for military aircraft will require capacitors with reliable performance at temperatures from -55 up to 300 degrees C and beyond for filters, power converters and other control circuitry. Thin film integrated passive devices with lower dissipation and electrical leakage will also be needed, especially at high frequencies. Thin films have inherently high bre ...

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 ...
