Fabrication of capacitively shunted high Tc Josephson junctions

Hysteretic high Tc Josephson junctions were fabricated by shunting grain boundary YBa2Cu3O7 junctions with a monolithic Au film capacitor. The junctions were made by pulsed laser deposition with ion milling, and the shunt capacitor by rf sputter deposition and lift-off. The McCumber parameter βc obt...

Description
Summary:Hysteretic high Tc Josephson junctions were fabricated by shunting grain boundary YBa2Cu3O7 junctions with a monolithic Au film capacitor. The junctions were made by pulsed laser deposition with ion milling, and the shunt capacitor by rf sputter deposition and lift-off. The McCumber parameter βc obtained from the measured current-voltage curves was much smaller (
