← ScienceWhich outcome results in Josephson junctions when insufficient pressure is applied?
A)Increased resonant electron pair tunneling
B)Reduced efficiency photon-phonon conversion
C)Increased Cooper-pair amplitude dissipation✓
D)Destabilized superconductivity near interfaces
💡 Explanation
Reduced pressure causes increased lattice spacing which weakens the *electron-phonon interaction*, destabilizing Cooper pairs; therefore amplitude dissipation increases, rather than enhanced tunneling, because superconductivity is weakened at tunnel barriers.
