← ScienceWhich material consequence occurs when thermal vibration disrupts crystal lattice periodicity?
A)Decreased piezoelectric effect efficiency
B)Increased electron-phonon scattering✓
C)Amplified quantum tunneling rate
D)Enhanced spin-orbit coupling strength
💡 Explanation
Increased electron-phonon scattering arises because lattice vibrations alter periodic potential, thus interrupting electron movement. This raises scattering, therefore lowering mobility rather than enhancing desirable quantum effects, which need lattice order.
