Which conduction effect occurs when thermal agitation narrows band gaps?

A)Increased intrinsic carrier concentration
B)Decreased electron-hole recombination
C)Reduced minority carrier diffusion
D)Enhanced piezoelectric polarization

💡 Explanation

Increased temperature reduces the energy required to excite electrons across the band gap, impacting **thermal excitation**; because more electrons jump the gap, intrinsic carrier concentration rises, therefore it conducts better rather than less, and no pressure involved.
