Which outcome arises when thermal vibration exceeds band-gap energy?

A)Semiconductor loses carrier confinement entirely
B)Increased piezoelectric voltage coefficient
C)Superconducting transition temperature increases
D)Ferromagnetic material's Curie temperature rises

💡 Explanation

Increased vibrations permit many electrons to jump across the **band gap**. Because increased numbers of carriers exist in the material's conduction band, the semiconductor's carrier confinement lowers; therefore the semiconductor conducts, rather than it remaining insulating at higher confinement from quantum effects in the material's crystalline structure band.
