2019-04-19 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. 2021-03-17 Quantum tunnelling has also been suggested as a way of harvesting energy from excess radiation and waste heat, so the more we understand about the way the process actually works, the better. In the meantime, the new research can be used as a basis for studying how other kinds of atoms tunnel through barriers and at what speeds – and that could potentially lead to a whole host of new Chemists at MIT and in South Korea have demonstrated characteristics of a phenomenon called quantum tunneling by using a very large electric field to alter the ability of ammonia molecules to switch between the normal and inverted states.

At its most basic and understandable explanation, quantum tunneling is the mechanical phenomenon where a wave function can propagate through a potential barrier.
The tunneling diodes and tunneling transistors are other devices which use this effect as
Quantum tunneling, as the name suggests, is a quantum phenomenon. Although tunneling has no counterpart in classical physics, it is an important consequence of quantum mechanics.

The quantum tunneling effect is a quantum phenomenon that occurs when particles move through a barrier that, according to the theories of classical physics, should be impossible to pass through. The barrier may be a physically impassable medium, such as an insulator or a vacuum, or a region of high potential energy.
