Which consequence occurs when a semiconductor's band gap narrows?

💡 Explanation

Increased sensitivity to thermal excitation arises because smaller band gaps allow thermally excited electrons to more easily jump to the conduction band, therefore conductivity increases due to this mechanism, rather than higher breakdown voltage.
