Quantum tunnelling or tunneling (see spelling differences) is the quantum mechanical phenomenon where a particle tunnels through a barrier that it classically cannot surmount.
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 (or tunneling) is the quantum-mechanical effect of transitioning through a classically-forbidden energy state. Consider rolling a ball up a hill.
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 ...

In tunnelling, a particle incident on one side of a potential can have a non-negligible probability to be found on the other side even if the potential is larger than the energy of the particle.

In the first part of a series on the history of quantum mechanics, Andrew Walker discusses a graphical method that works wonders to develop a physical intuition for quantum mechanical tunneling.
Jon Butterworth: Quantum tunnelling sounds like science fiction, and does indeed feature there quite often. But it is real, and plays a role in nuclear fusion, chemical reactions and the fate of the universe.
Quantum mechanical tunneling plays important roles in a wide range of natural sciences, from nuclear and solid-state physics to proton transfer and chemical reactions in chemistry and biology. Responding to the need for further understanding of multidimensional tunneling, the authors have recently ...
Quantum Tunneling :. The phenomenon of tunneling, which has no counterpart in classical physics, is an important consequence of quantum mechanics.
In quantum mechanics, the rectangular (or, at times, square) potential barrier is a standard one-dimensional problem that demonstrates the phenomena of wave-mechanical tunneling (also called "quantum tunneling") and wave-mechanical reflection.
Quantum Tunneling is an evanescent wave coupling effect that occurs in quantum mechanics. The correct wavelength combined with the proper tunneling barrier makes it possible to pass signals faster than light, backwards in time.
