Abstract : Through the use of numerical methods involving both the drift and diffusion equations including traps, and more recently the quantum Liouville equation, Scientific Research Associates, Inc., (SRA) has been examining the physics and operation of LTG materials and devices. Both defect and Schottky models have been studied, and two-dimensional microscopic and macroscopic device simulations have been performed. A new generalization of the drift and diffusion equations, including current, has been implemented for the specific purpose of treating embedded metallic precipitates. This document summarizes SRA work under U.S. Air Force, Office of Scientific Research, Contract # F49620-9 1 -C-0023. jg
