← ScienceWhich consequence results when high-energy photons strike a crystalline semiconductor?
A)Significant electron-hole pair generation increases✓
B)Phonon population decreases towards ground state
C)Crystal lattice destabilization precedes amorphization
D)Material temperature decreases towards absolute zero
💡 Explanation
Band gap absorption causes electron-hole pairs to forms because photons with energy exceeding the band gap excite electrons, leading to greater conductivity and pair creation; therefore, option A, rather than B or C, is direct energy conversion in semiconductors.
