Superconducting Ba sub 1 sub - sub x K sub x BiO sub 3 thin films and junctions

Superconducting BKBO thin films and heteroepitaxial multilayers were deposited on various substrates at 400 degrees C. NIS-type tunnel junctions with native insulator layer and deposited MgO layer were reproduced. With an MgO insulator layer thickness of 3 nm, SIS tunnel junctions with Josephson sup...

Zusammenfassung:Superconducting BKBO thin films and heteroepitaxial multilayers were deposited on various substrates at 400 degrees C. NIS-type tunnel junctions with native insulator layer and deposited MgO layer were reproduced. With an MgO insulator layer thickness of 3 nm, SIS tunnel junctions with Josephson supercurrent were obtained with hysteretic I-V characteristics.
