← ScienceWhich mechanism causes thermal resistance to increase within solid-state thermoelectric modules?
A)Phonon scattering at lattice imperfections✓
B)Electron tunneling across grain boundaries
C)Magnon interactions at Curie temperature
D)Polaron hopping between defect sites
💡 Explanation
Phonon scattering increases thermal resistance because crystal lattice dislocations disrupt phonon propagation, therefore reducing thermal conductivity rather than increased electron transfer or magnetic effects that occur under different mechanisms.
