← ScienceWhich outcome occurs when a Josephson junction contains excessive copper oxide?
A)Suppressed critical current through oxidation
B)Elevated junction resistance dominates current✓
C)Increased electron quantum resonant tunneling
D)Enhanced Cooper triplet pair separation efficiency
💡 Explanation
Elevated junction resistance results because copper oxide acts as an insulator, therefore inhibiting Cooper pair tunneling, rather than facilitating it. This effect masks the superconducting properties because the insulating layer impedance dominates.
