Which outcome occurs when a crystalline silicon lattice imperfection increases?

A)Reduced electron mobility results
B)Increased thermal conductivity results
C)Enhanced piezoelectric effect appears
D)Higher transition temperature appears

💡 Explanation

Reduced electron mobility happens because increased imperfection introduces phonon scattering of the “electron wave,” a wave-particle duality mechanism. Therefore, mobility decreases, rather than improved conduction which requires lattice regularity under thermal motion.
