When an electric field is applied, the electrons move from an energetically higher lying potential well to an energetically lower lying potential well via the quantum mechanical tunneling effect.

A microscopic method for simulating quantum mechanical, nuclear tunneling effects in biological electron transfer reactions is presented and applied to several electron transfer steps in photosynthetic bacterial reaction centers.

«Going back to the first example,» say the authors, «super coupling means that all the light will be transferred from one side of the wall to the other through any shape of hole we want to make; tunnel effect refers to light passing through a hole of any length, no matter how long we want to make it; and the confining of energy is due to the fact that the light is transferred even through very small holes, so the energy inside the hole is squeezed enormously.»

In theory, explained Dr. Cheng, «This would produce a unique tunneling effect and an unprecedented property that the output waveform is kept consistent with those of the waves traveling toward a boundary.»

Carbon tube walls are good conductors, and along the gap between the ends of the nanotubes the current flows thanks to the tunnel effect, which is a quantum phenomenon where electrons pass through a barrier that is considered insurmountable in classical mechanics.

«The tunnel effect has definitely reached the quantum limit here,» says team member Berthold Jäck.

(*) But only up to a certain point: electrodes that are too close are subject to the quantum tunneling effect, and the current between them is no longer controllable.

Among the electromagnetic metamaterials, the above - mentioned ENZ ones make it possible to achieve the super coupling of the light, the tunnel effect and the confining of energy in tiny spaces.

A strong laser pulse is directed at a molecule, which causes electrons to break away due to the quantum tunneling effect.

About ten years ago, after ferroelectric properties were demonstrated in ultra-thin single - crystal films of perovskites, an alternative concept for memory devices was proposed — based on the use of the tunnel effect.

However, if the ferroelectric layer is very thin, electrons can «slip» through with a certain probability, thanks to the quantum tunnelling effect.

But as the size of modern transistors continues to shrink, the gate material becomes so thin that it can no longer block electrons from leaking through — a phenomenon known as the quantum tunneling effect.
