Step-edge Josephson junctions on multilayered high temperature superconducting thin film

Journal Article


Abstract


  • Application of Josephson effect in sensors, electronic

    and metrological devices working at temperature of 77 K requires

    fabrication of efficient and reproducible high temperature superconducting

    (HTS) Josephson junctions. In order to enhance

    the performance of HTS junctions, we introduce multilayered

    approach to YBCO-based step-edge Josephson junction manufacture.

    Thin YBCO and multilayered YBCO/NdBCO/YBCO films

    of a similar thickness (~210 nm) were grown by a pulsed-laser

    deposition technique on MgO (100) substrates with artificially

    created step edge. Large discrepancies of Ic and Rn values were

    found between these two types of junction. Results of their structural

    and electrical properties are reported.
