← ScienceWhich consequence results when point defects concentrate inside semiconductor crystal?
A)Increased electron-hole recombination occurs✓
B)Enhanced phonon transport emerges
C)Higher frequency current oscillation forms
D)Increased intrinsic carrier densities develop
💡 Explanation
Higher defect concentration forms recombination centers; therefore, electron-hole recombination rate increases because Shockley-Read-Hall recombination dominates, rather than increased carrier density caused intrinsic excitation that point defects cannot affect.
