quantum mechanical tunneling

Quantum tunnelling - Wikipedia

Quantum tunnelling or tunneling (see spelling differences) is the quantum mechanical phenomenon where a particle tunnels through a barrier that it classically cannot surmount.

Quantum Mechanical Effect of Electron Tunneling

Wave and particle properties of electrons according to quantum mechanics. Electrons tunnel through thin barriers. The resulting current is used for STM measurements.

Quantum tunnelling - ScienceDaily

Quantum tunnelling (or tunneling) is the quantum-mechanical effect of transitioning through a classically-forbidden energy state. Consider rolling a ball up a hill.

6.5: Quantum Mechanical Tunneling - Chemistry LibreTexts

Quantum mechanical tunneling is a consequence of the fact that a vibrating molecule has a significant probability to be in the classically forbidden region of space, i.e. beyond the classical limit. Suppose that rather than having a harmonic potential for the displacement of an atom from its ...
