ABSTRACT:
A superconducting Josephson junction is created in high T.sub.c superconducting film, with a bridge connecting two superconducting banks, by subjecting the bridge to a tunneling electron current from a sharp electrode close to the bridge. The tunneling current alters the structure over atomic dimensions to create a weak link of length comparable to high T.sub.c coherence lengths so as to permit phase coherent Cooper pair current flow across the weak link.
