In situ pulsed laser deposition of superconducting Ba(1-x)K(x)BiO3 thin films

Superconducting thin films of Ba(1-x)K(x)BiO3 were grown by in situ pulsed laser deposition from a stoichiometric (x = 0.4) target. The best films exhibit an onset transition temperature of 28 K and have zero resistance as high as 26 K. Films are single phase and highly oriented in the (100) or (110...

Zusammenfassung:Superconducting thin films of Ba(1-x)K(x)BiO3 were grown by in situ pulsed laser deposition from a stoichiometric (x = 0.4) target. The best films exhibit an onset transition temperature of 28 K and have zero resistance as high as 26 K. Films are single phase and highly oriented in the (100) or (110) direction on MgO, SrTiO3, LaAlO3, and Al2O3 substrates. High-quality normal-insulator-superconductor and superconductor-insulator-superconductor quasi-particle tunneling characteristics were observed with the films. (Author)
