Type of article: Article

Summary

JOSEPHSON JUNCTIONS ARE ELECTRONIC DEVICES MADE FROM SUPERCOND UCTING MATERIALS THAT CYCLE BETWEEN RESISTIVE AND NON RESISTIVE STATES. HEAT GENERATED IN THE RESISTIVE STATE CAUSES A TEMPERATURE RISE, WHICH MAY ADVERSELY AFFECT ELECTRICAL BEHAVIOUR, BY REDUCING THE CRITICAL JOSEPHSON CURRENT. IN THE PAPER, TEMPERATURE DISTRIBUTIONS AND RESULTING REDUCTIONS IN CRITICAL CURRENT ARE CALCULATED FOR JOSEPHSON JUNCTIONS MADE FROM LOW AND HIGH-TEMPERATURE SUPERCONDUCTORS. IT IS FOUND THAT AN UNACCEPTABLE REDUCTION IN CRITICAL CURRENT MAY OCCUR FOR JUNCTIONS MADE FROM HIGH-TEMPERATURE MATERIALS. THIS PROBLEM CAN ALMOST CERTAINLY BE OVERCOME, BUT PERHAPS AT THE EXPENSE OF ONE ADVANTAGE OF JOSEPHSON JUNCTIONS, NAMELY COMPACTNESS.
