Window-type tunnel devices on YBa2Cu3O7-x thin films
1991
Superconductor Science & Technology
The authors present the first YBa2Cu3O7-x-Pb tunnelling measurements using window-type tunnel devices. YBa2Cu3O7-x (YBCO) thin films are grown in-situ by dual Ar+ ion beam sputtering. Tunnel barriers are formed on a chemically etched YBCO surface. Tunnelling dV/dI(V) characteristics show reproducible weak gap-like structure 4.4±0.4 meV and 22±2 meV, the latter giving a 2Δ/kBTc value of about 6.5
