Synthesis and Study of High-Tc Superconducting Electronic Materials
Abstract
The research program described here was designed to contribute to the evaluation of high T (sub c) superconducting materials for usefulness in electronic circuitry. The experimental techniques emphasized in this plan included electron tunneling and the use of intense magnetic fields to obtain information about the electronic properties of thin films of these materials. The superconductors studied included BiSrCaCuO, NdCeCuO, and BaKBiO. Thin films were formed by pulsed laser ablation, magnetron sputtering, and molecular beam epitaxy. In addition to obtaining electronic transport and tunneling data on these materials, a technique was found to make high-quality superconductor- insulator-superconductor tunnel junctions using artificial grain boundaries. This technique is the only one thus far discovered for making all-thin-film quasiparticle tunnel junctions reliably from high T (sub c) materials.
