Which outcome occurs when a voltage-biased nanoscale gap constrains electron flow?

💡 Explanation

Quantum tunneling creates a current because there's a probable wavefunction overlap across the gap, even though classically forbidden; therefore, electrons tunnel to the other side, rather than waiting for the voltage to overcome the gap through dielectric breakdown.
