Which outcome results when thermal energy increases in semiconductor junctions?

A)Band gap energy decreases overall
B)Increased electron-phonon mean free path
C)Fermi level aligns with mid-gap
D)Coherent phonon scattering reduces resistance

💡 Explanation

The band gap decreases because increased thermal energy excites more electrons across the band gap, using more energy to break the bonds responsible for the band gap in a process called band gap renormalization, thus reducing the gap width overall rather than creating free carriers.
