← ScienceWhich outcome occurs when a semiconductor diode's band gap energy matches incident photon energy?
A)Electron-hole pair generation increases sharply✓
B)Reverse bias current becomes saturated.
C)Barrier potential dramatically increases.
D)Depletion region width reaches minimum.
💡 Explanation
Maximum electron-hole pairs are generated because photons elevate electrons across it via band gap absorption; therefore current increases because of increased mobile chargers rather than any voltage alteration, under different conditions.
