The investigation of transport properties on Y1Ba2Cu3O7−x step edge junctions by ion beam etching
We have investigated the transport of Y1Ba2Cu3O7-x (YBCO) step edge junctions with a wide range of normal resistance Rn, which were obtained by ion beam etching (trimming) the YBCO thin film on the junction area. A SS'IS'S junction model (S: superconductor, S': superconductor with a r...

| Zusammenfassung: | We have investigated the transport of Y1Ba2Cu3O7-x (YBCO) step edge junctions with a wide range of normal resistance Rn, which were obtained by ion beam etching (trimming) the YBCO thin film on the junction area. A SS'IS'S junction model (S: superconductor, S': superconductor with a reduced order parameter and I: insulator) has been used to explain the change of the junction parameters after trimming. It is noticed that there is a reduction of both superconducting order parameter and the effective area on S' after trimming. |
