Title:
HIGH-TEMPERATURE SUPERCONDUCTOR JOSEPHSON TUNNEL JUNCTION
Document Type and Number:
WIPO Patent Application WO/2004/027885
Kind Code:
A1
Abstract:
Two single crystals of high-temperature superconductor are arranged on a substrate to intersect each other at a crossing angle of 0-90 degree and bonded together, thereby forming a single high-temperature superconductor Josephson tunnel junction at the bonded portion. The plasma frequency of the high-temperature superconductor Josephson tunnel junction changes in accordance with the crossing angle.
