Science

Which consequence results when a semiconductor's band gap decreases with temperature?

A)Increased electron-hole pair generation
B)Reduced intrinsic carrier concentration
C)Higher breakdown electrical field
D)Decreased material thermal expansion

💡 Explanation

Increased temperature narrows the band gap, which enhances the rate of electron-hole pair generation because thermal energy exceeds the reduced band requirement. Therefore, more charge carriers are available, rather than showing decreased concentrations due to widening band gaps at low temperatures.
