Which risk increases when exceeding a semiconductor's bandgap energy?

A)Free carrier generation escalates rapidly
B)Phonon dispersion becomes rate-limiting
C)Quantum tunneling probability decreases
D)Exciton binding energy dramatically decreases

💡 Explanation

Electron-hole pairs proliferate via intrinsic excitation because increased photon energy triggers band-to-band transitions. Therefore, free carrier generation escalates as photons exceed bandgap limits, rather than stable excitations.
