← ScienceWhich consequence results when applying excessive voltage across solid lead-sulfide?
A)Increased intrinsic carrier concentration.
B)Augmented ionic Frenkel defect population.✓
C)Elevated electron-phonon scattering rate.
D)Decreased Auger recombination lifetimes.
💡 Explanation
Increased voltage biases the formation energy, therefore *interstitial defect* populations grow; because applied energy surpasses lattice binding, rather than changing intrinsic properties, electron scattering, or recombination rates.
