← ScienceWhich outcome occurs when dopants break crystal symmetry?
A)Increased electron-phonon scattering rate✓
B)Enhanced radiative recombination efficiency
C)Suppressed second harmonic generation
D)Increased ferromagnetic Curie temperature
💡 Explanation
Increased electron-phonon scattering occurs because dopants disrupt the periodic lattice, which introduces defects; therefore, phonon scattering increases. Lower scattering happens in a pure, crystalline lattice rather than with defect-induced mechanisms.
