← ScienceWhich outcome occurs when photons of specific energies strike a silicon crystal, due to its electronic band structure?
A)Electron-hole pairs are generated near threshold.✓
B)Complete reflection occurs due to inductance.
C)Phonon modes shift to lower energies.
D)Increased polarization reverses dielectric alignment.
💡 Explanation
Electron-hole pair generation occurs because photon energy matches the band gap's threshold, leading to electron excitation across the energy gap. Therefore, electron-hole pairs increase, rather than reflection or alteration of material properties.
