Which outcome results when electron's wave function has non-zero amplitude beyond gate?

💡 Explanation

Quantum tunneling allows an electron to penetrate a potential barrier because the wave function extends beyond the gate, therefore resulting current flow in a transistor; rather than alternative failure modes involving capacitance or thermal effects.
