Which mechanism enables an electron's traversal of an electrical insulator?

💡 Explanation

Quantum tunneling allows electrons to pass through a barrier, because the transmission probability increases exponentially as the barrier width decreases; therefore, quantum tunneling allows electrons to traverse the insulator rather than being blocked like in classical physics.
