Which outcome occurs when electrons approach a thin insulating layer?

💡 Explanation

Quantum tunneling allows some electrons to pass through the insulating layer, even if their energy is lower than the potential barrier, because wavefunctions have non-zero amplitudes; therefore, penetration occurs rather than complete reflection or heating.
