Science

Which consequence results when the Fermi-Dirac distribution function broadens at higher temperatures in a semiconductor?

A)Reduced electrical conductivity overall
B)Increased electron-hole pair generation
C)Decreased intrinsic carrier concentration
D)Suppressed thermal runaway effect

💡 Explanation

Broadening occurs because thermalexcitation allows electrons to overcome energy barriers more easily, increasing electron-hole pair generation, leading to more carriers; therefore higher temperature enhances conductivity rather than decreasing electron-hole pairs under normal cases.
