Which outcome is likely when electrons undergo wave function overlap?

💡 Explanation

Quantum tunneling through potential barriers occurs because wave function overlap gives a non-zero probability for electrons to exist on the other side of the barrier. Therefore, tunneling occurs, rather than the electron being confined; this doesn't directly affect either current flow or phonon scattering.
