Which consequence results when an alloy's energy band gap overlaps defect states?

💡 Explanation

Increased electron-hole recombination occurs because defect states within the overlap facilitate electron transitions from the conduction band to the valence band through Shockley-Read-Hall recombination. Therefore, option B is the correct event, rather than enhanced conductivity options due to carrier losses.
