Which outcome arises when electrons encounter a nanomaterial's band gap?

💡 Explanation

Electrons can tunnel through a potential barrier due to their wave-like nature; this quantum mechanical tunneling is the mechanism. Therefore, tunneling results despite the forbidden energy gap, because instead, a barrier height limits electron transmission rather than blocking it outright.
