Enhancement of high-TCsuperconducting thin film devices by nanoscale polishing

Abstract: The effects of mechanical nanoscale polishing on the superconducting parameters of YBa2Cu3O7−δ (YBCO) thin films and bi-crystal grain boundary Josephson junctions have been investigated. We prepared samples with additional gold nanocrystallites in the YBCO film. As they are distributed throughout the whole YBCO film, they provide a low-resistance ohmic contact even if parts of the film are removed. Polishing was performed either before or after the patterning and did not change the properties of the grain bou… Show more

“…Polishing the crystal surface to an RMS roughness ⩽5 nm is necessary in order to prepare these junctions using photo lithography, sputtering and ion beam etching (IBE). While there are some publications concerning the polishing of different unconventional superconductor materials [5][6][7], it is necessary to consider special requirements for the polishing procedure for the preparation of devices on pnictides, which were not fully met in the mentioned works. Ba-122 is sensitive to water and acetone, meaning the polishing solvant and the cleaning steps had to be adapted.…”
