← ScienceWhich outcome inhibits current when energy approaches band gap?
A)Increased electron-hole recombination process✓
B)Elevated plasmon resonance frequency
C)Enhanced phonon-electron scattering rates
D)Decreased dielectric breakdown susceptibility
💡 Explanation
Increased electron-hole recombination diminishes conductivity. Near the band gap, injected energy drives electrons across, but **electron-hole recombination** dominates because excited electrons readily fall back into holes, rather than contributing to current; therefore conductivity decreases rather than increases.
