← ScienceWhich temperature consequence results when phonon scattering increases in crystalline lattice?
A)Decreased thermal conductivity occurs overall✓
B)Increased Seebeck coefficient functionality
C)Enhanced thermoelectric generator efficiency
D)Faster electron mobility semiconductor performance
💡 Explanation
Increased phonon scattering impedes lattice vibration's transport energy, because the phonons collide and transfer energy randomly, therefore causing decreased thermal conductivity, rather than directional heat flow implied by increased efficiency.
