Electrical conduction mechanisms of metal / high-Tc superconductor (YBCO) interfaces

L. F. Lanosa, H. Huhtinen, P. Paturi +1

Current-voltage characteristics of Au~/~YBa${}_2$Cu${}_3$O${}_{7-\delta }$ interfaces (Au/YBCO), built on optimally-doped YBCO thin films, grown by pulsed laser deposition, were measured as a…
