Which risk increases significantly when exceeding the Debye temperature of a superconducting lattice?

A)Increased electron-phonon scattering
B)Enhanced Cooper pair formation
C)Diminished Meissner effect magnitude
D)Suppressed Josephson junction tunneling

💡 Explanation

Exceeding the Debye temperature causes rising phonon populations promoting electron-phonon scattering, because the thermal energy surpasses the lattice vibrational energy. Therefore, superconductivity diminishes rather than enhances, because scattering disrupts Cooper pairs.
