Which outcome occurs when the band gap decreases in a photodiode?

💡 Explanation

Increased reverse current leakage occurs, because a smaller band gap allows thermally excited electrons to jump across the junction more easily via thermal excitation, and then contribute to the reverse current. Therefore leakage increases, rather than requiring incoming photons because it allows more carriers to tunnel.
