Organized Nanorod-Superconductor Composites (Publications/Patents/Presentations/Honors/Students Report),
Abstract
The overall goal of this project is to develop rational approaches for controlling the structure and interfaces of high-temperature superconductors (HTSs) and other complex solids at the nanometer scale. Our emphasis on nanometer scale is motivated by the recognition that control of structure in this size regime leads in general to materials with enhanced and/or novel electrical, mechanical, optical and magnetic properties. In this regard, our main objective has been to control the nanometer scale defect structure in HTSs since this will enable the intrinsic problem of thermally-activated flux flow, which limits critical currents in all HTS materials, to be significantly reduced. Specific objectives that have been pursued during the past year include (1) the design and synthesis of one-dimensional nanostructures (nanorods) that are chemically and structurally compatible with HTS materials, (2) the synthesis and structural characterization of nanorod/HTS nanocomposites, and (3) the elucidation of critical current behavior of nanorod/FiTS materials as a function of temperature and magnetic field.
