When a Josephson junction's oxide barrier narrows, which phenomenon dominates current flow?

A)Quantum tunneling increases sharply
B)Thermal excitation overcomes resistance
C)Capacitive reactance becomes infinite
D)Magnetic flux induces back EMF

💡 Explanation

Quantum tunneling dominates at very thin barriers because electrons pass through despite the barrier via wave function overlap; therefore the current jumps rather than decreasing because thermal effects are less significant here.
