← ScienceWhich phenomenon hinders electron flow when thermal energy perturbs a metallic crystal?
A)Increased phonon scattering✓
B)Augmented band gap width
C)Enhanced plasmon resonance
D)Elevated Cooper pair density
💡 Explanation
Increased thermal energy within the metallic crystal enhances atomic vibrations; phonon scattering then increases, because they disrupt electron movement through the lattice. Therefore electron flow decreases, rather than increasing, plasmon resonance, or Cooper pair density, caused by separate quantum behaviours.
