Abstract

A description is given of the fabrication method and Josephson properties of high temperature superconducting junctions produced by focused electron beam writing. The nature of a weak link, I-V characteristics, transition to flux flow, and magnetic field modulation are discussed in some detail. The materials aspects such as the mechanism of e-beam damage to HTS, threshold energy, junction stability, and some technological issues such as reproducibility and uniformity are also addressed.
