Sentences with phrase «quantum tunneling 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.

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

This is achieved by the quantum tunneling effect — the ability of an electron to pass through a barrier.

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

Not exact matches

The group calculated that an electron could «tunnel» through the barrier imposed by the odorant, an effect made possible by quantum mechanics, they wrote in a preprint accepted for publication in Physical Review Letters.

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

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.

About a dozen possible next - generation candidates exist, including tunnel FETs (field effect transistors, in which the output current is controlled by a variable electric field), carbon nanotubes, superconductors and fundamentally new approaches, such as quantum computing and brain - inspired computing.

This effect is the converse of the well - known (if no less astounding) phenomenon of quantum tunneling.

On a more practical level, the Uncertainty Principle explains numerous real, observed physical effects, such as quantum tunneling.

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.

Thus the lighter helium isotope is, as it were, outside of the bowl but, due to the quantum mechanical tunnel effect, it still «notices» the atoms in the bowl and can not simply fly away.»
