Which outcome reduces electron mobility in crystal lattice?

💡 Explanation

Phonon scattering reduces mobility because lattice vibrations (phonons) deviate electrons from their path, impeding consistent movement. Therefore, electron mobility decreases rather than increasing, because electrons scatter off impurities or imperfections within the lattice.
