← ScienceWhich mechanism prevents effective heat transfer above a superconducting transition temperature?
A)Scattering of quasiparticles✓
B)Increased lattice vibrations
C)Formation of Cooper pairs
D)Suppressed electron-phonon coupling
💡 Explanation
Above the superconducting transition temperature, normal electrons exist; quasiparticle scattering dominates because these electrons impede heat flow, therefore decreasing thermal conductivity, rather than phonon effects being primary at higher temperatures.
