Abstract:In this work we briefly overview various options for Josephson junctions which should be scalable down to nanometer range for utilization in nanoscale digital superconducting technology. Such junctions should possess high values of critical current, Ic, and normal state resistance, Rn. Another requirement is the high reproducibility of the junction parameters across a wafer in a fabrication process. We argue that Superconductor -Normal metal -Superconductor (SN-N-NS) Josephson junction of "variable thickness b… Show more
