Resonant tunneling through Quantum dot arrays is the quantum-mechanical effect of transition through a classically-forbidden energy state.
Consider rolling a ball up a hill. If the ball is not given enough velocity, then it will not roll over the hill. This makes sense classically. But in quantum mechanics, objects exhibit wavelike behaviour. For a quantum particle moving against a potential hill, the wave function describing the particle can extend to the other side of the hill. This wave represents the probability of finding the particle in a certain location, meaning that the particle has the possibility of being detected on the other side of the hill. This behavior is called tunneling; it is as if the particle has ‘dug’ through the potential hill.
As a consequence of the wave-particle of matter, tunneling is often explained using the Heisenberg uncertainty principle. Purely quantum mechanical concept is the focus of the phenomenon, so quantum tunneling is one of the defining features of quantum mechanics and the particle-wave duality of matter.
As a consequence of the wave-particle of matter, tunneling is often explained using the Heisenberg uncertainty principle. Purely quantum mechanical concept are the focus of the phenomenon, so quantum theory, de Broglie introduced a fundamental hypothesis the matter has duality of matter.
In 1923, during the early stage of quantum theory, de Broglie introduced a fundamental hypothesis the matter has dualistic nature. Quantum tunneling is one of the defining features of quantum mechanics and the particle-wave duality of matter.
