Which consequence results when localized defects modulate semiconductor band structure?

A)Increased electron-hole recombination rate✓

B)Higher intrinsic charge carrier mobility

C)Reduced rate of spontaneous polarization

D)Suppressed Auger scattering process

💡 Explanation

Recombination increases greatly because defects introduce energy levels within the band gap, enabling electrons and holes trap then annihilate, therefore raising surface recombination, rather than altering mobility/polarization because it’s a localized rather than bulk effect.
