This report consists of three parts: an Ohio State Electrical & Computer Engineering /Physics component, an Ohio State Electrosciences component, and a Wright State component. This research effort addresses the need for high performance radio frequency (RF) components, specifically varactors and miniaturized, high gain, high bandwidth antennas. This program encompasses materials design, growth, processing, and physical characterization to develop varactor and antenna components with low dielectric loss. This program of research represents the second stage of the MultiFunctional oxide Materials, their Applications (MFMA) and devices initiative, which seeks to leverage Ohio strengths in oxide materials, magnetics and telecommunications into state-of-the-art electromagnetic technology that can revolutionize products in communications, sensors, and radar. Functional epitaxial oxide devices based on MFMA technology can enhance telecommunication (both wired and wireless, and optical), present-day computers, and provide technologies for nonvolatile data storage, sensors for defense and commercial application. This Ohio effort coordinates with complementary growth, characterization and device fabrication activities of Prof. Hadis Morkoc at Virginia Commonwealth University., The original document contains color images. All DTIC reproductions will be in black and white.

We have acquired an Auger Electron Spectroscopy Microprobe Analysis System for elemental and bonding analysis of electronic materials, equipped with specimen stage, ion beam depth analyzer, and ultrahigh vacuum (UHV) preparation chamber interfaced to an existing UHV scanning electron microscope. The specific equipment purchased is: JEOL USA, Inc. Auger Electron Spectroscopy Depth Profiling Hardware and Software for the JAMP-7800 deg F. Its acquisition enhances a number of DoD-funded programs and student training that involve development of high power and high frequency electronic materials with superior performance, especially improving the state-of-the-art and availability of radiation-tolerant semiconductor electronics for applications in the space environment investigators.
