Interface-engineered Josephson junctions optimized for high JC.

Interface-engineered Josephson junctions optimized for high JC.

High-temperature superconducting interface-engineered junctions were fabricated using YBa2Cu3O7-δ on LaAlO3 (LAO) and sapphire substrates. We report on the improvements in the electrical characteristics by junction narrowing. Originally, the 2-μm-wide junctions had high critical current densities of...
