← ScienceWhich outcome abruptly occurs when electron energy exceeds a semiconductor's band gap?
A)Avalanche breakdown within internal electric fields
B)Increased phonon scattering inhibiting carrier mobility
C)Increased electron-hole recombination generating light✓
D)Exciton formation leading to optical transparency
💡 Explanation
Increased electron-hole recombination will occur because exceeding the band gap provides sufficient energy for electrons to jump to the conduction band; the subsequent recombination releases energy as photons. Therefore, increased light output, rather than breakdown or transparency, results.
