In quantum mechanics, the situation is not so simple. The particle can escape even if its energy E is below the height of the barrier V , although the probability of

Quantum tunneling which was developed from the study of radioactivity is usually explained in terms of the Heisenberg uncertainty principle. To put it simply, the uncertainty in knowing the exact location and momentum of quantum particles allows these particles to break rules of classical mechanics and move in space without passing over the potential energy barrier.

Although tunneling has no counterpart in classical physics, it is an important consequence of quantum mechanics. It is basically a phenomenon in which particles move through a barrier that is otherwise forbidden according to classical physics laws. 2013-02-24 · Tunneling in Your Gadgets. Quantum tunneling isn’t just relevant for exotic states of matter. The scanning tunneling electron microscope uses this effect too. To measure the shape of a surface to very high resolution, it applies a voltage to the surface and the opposite voltage to a short piece of wire.

The particle can escape even if its energy E is below the height of the barrier V , although the probability of escape is small unless E is close to V . In that case, the particle may tunnel through the potential barrier and emerge with the same energy E. Figure \(\PageIndex{3}\): Quantum tunnelling through a barrier. At the origin (x=0), there is a very high, but narrow potential barrier.

Quantum tunneling oscillations of probability in an integrable double well of potential, seen in phase space. The concept of quantum tunneling can be extended to situations where there exists a quantum transport between regions that are classically not connected even if there is no associated potential barrier. Quantum tunneling refers to the nonzero probability that a particle in quantum mechanics can be measured to be in a state that is forbidden in classical mechanics. Quantum tunneling occurs because there exists a nontrivial solution to the Schrödinger equation in a classically forbidden region, which corresponds to the exponential decay of the magnitude of the wavefunction .
