Which outcome occurs when a semiconductor crystal lattice absorbs photons near its characteristic wavelength?

💡 Explanation

Electron-hole pairs increase because photon absorption leads to band-to-band excitation, a process where electrons gain energy to jump across the band gap. Therefore, conductance rises, rather than softening from phonon scattering and recombination stabilises, suppressing lattice defects.
