Which consequence results when quantum tunneling is increased sharply across overlapping atomic orbitals?

A)Increased electron mobility results directly
B)Band gap widens unexpectedly
C)Decreased electron effective mass
D)Fermi level stabilizes and equilibrates

💡 Explanation

Increased quantum tunneling raises electron availability which causes delocalization, therefore increased electron mobility results, because electrons travel more freely through the material, rather than being localized, decreasing conductivity otherwise.
