Sentences with phrase «electron tunneling barriers»

Applications for this research demonstrate implications for use in materials like abrasion resistant paints, high surface area catalyst, electron tunneling barriers, ultra-violet adsorption or capture in sunscreens or solar cells and even beyond when core - shell nanoparticles are used as buildings blocks for making new artificial nanostructured solids with unprecedented properties.

Not exact matches

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

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.

That jolt weakens the electromagnetic barrier just enough that electrons can leave, but only by tunneling.

Each time a packet of electrons tunneled through the barrier, the team was able to measure a current using remote electrodes.

Electrical current is injected into the device, tunnelling from single - layer graphene, through few - layer boron nitride acting as a tunnel barrier, and into the mono - or bi-layer TMD material, such as tungsten diselenide (WSe2), where electrons recombine with holes to emit single photons.

The devices are named after Brian Josephson, who predicted in 1962 that pairs of superconducting electrons could «tunnel» right through the nonsuperconducting barrier from one superconductor to another.

The laws of quantum mechanics allow pairs of electrons to «tunnel» through the barrier only very occasionally — helping the team to isolate and control the pairs as they slowly break out.

Hawking radiation is based on the well established fact of quantuum tunneling where a particle may disappear at one point in space and reappear at another point without enough energy to have moved across a barrier from point A to point B. Flash memory chips work by quantuum tunneling where an electron is raised to an energy level just short of being able to cross a barrier into a holding pen.

The electron then tunnels through the barrier and its energy level is reduced such that the probability of it tunnelling back in the other direction is so small you count on it never happening.
