ALTERNATIVE MATERIALS FOR RAMP-EDGE SNS JUNCTIONS

Creators

Description

We report on the processing optimization and fabrication of ramp-edge high-temperature superconducting junctions by using alternative materials for both superconductor electrodes and normal-metal barrier. By using Ag-doped YBa2Cu3O7-x (Ag:YBCO) as electrodes and a cation-modified compound of (PryGd0.6-y)Ca0.4Ba1.6La0.4Cu3O7 (y = 0.4, 0.5, and 0.6) as a normal-metal barrier, high-temperature superconducting Josephson junctions have been fabricated in a ramp-edge superconductor/normal-metal/superconductor (SNS) configuration. By using Ag:YBCO as electrodes, we have found that the processing controllability /reproducibility and the stability of the SNS junctions are improved substantially. The junctions fabricated with these alternative materials show well-defined RSJ-like current vs voltage characteristics at liquid nitrogen temperature
