← ScienceWhich mechanism causes abrupt resistance loss as temperature drops?
A)Cooper pair formation via phonon mediation✓
B)Increased electron-phonon scattering events
C)Enhanced thermal energy carrier transitions
D)Suppressed magnon induced spin fluctuations
💡 Explanation
Superconductivity arises because *Cooper pair formation via phonon mediation* causes electrons to couple, forming pairs and moving without resistance. The material enters a superconducting state, therefore current flows freely, rather than electrons scattering and losing energy.
