摘要：
Ramp-type Josephson junctions with YBCO superconducting electrodes and PrBa2Cu2.6Ga0.4O6+δ (PBGCO) barriers were fabricated and characterized. The YBCO ramp junctions with 25 nm-thick barriers of PBGCO showed typical resistively-shunted-junction (RSJ)-like I-V behavior and 1 σ spread of less than 13% in critical current density. Differential conductance-voltage characteristics registered using a lock-in technique indicate that the resonant tunneling via localized states in the barriers plays a dominant role in the conduction process of the ramp junctions.
