Which consequence results when a semiconductor manufacturing process introduces metallic impurities into crystalline silicon?

💡 Explanation

Increased metallic impurities within the silicon crystal structure creates trap states within the band gap, leading to increased electron-hole recombination rate because these impurities disrupt the ideal sp3 hybridization of silicon's molecular orbitals. Therefore, recombination increases, rather than enhanced conduction or excitons, as the excited electrons decay faster.
