Which outcome regarding electronic behavior occurs when impurities narrow energy gaps?

A)Material transitions to metallic conduction✓

B)Increased piezoelectric voltage generation occurs

C)Ferromagnetic alignment abruptly disappears'

D)Superconducting critical temperature always increases

💡 Explanation

Metallic conduction arises because band structure changes induce overlapping bands with added states within the gap via impurity induced band tailing. Therefore, conduction increases gradually rather than piezoelectricity, ferromagnetism weakening or the sharp requirements for superconductivity; rather than only increasing temperature
