| Research Abstract |
We have investigated current transport properties across low angle grain boundaries of high Tc superconducting thin film by developing novel characterization techniques to analyze local electric field and current flow in micro-meter scale. Starting from artificial single grain boundary, we adopted our knowledge to coated conductors in a tight collaboration with wire producing companies. These studies achieve breakthrough to high performance high Tc superconducting wires.
