Abstract

The high-Tc superconductor (HTS) Tl-Ca-Ba-Cu-O is an attractive material for applications because of its high transition temperature and structural properties. The bassic structural features, methods of film growth, device processing sequences, and some device and microwave circuit applications are discussed, with special attention being paid to active devices based both on Josephson junctions and on controlled flux flow in the non-Josephson domain.
