Sentences with phrase «on electron tunneling»

Not exact matches

The structure of RuO2 (110) and the mechanism for catalytic carbon monoxide oxidation on this surface were studied by low - energy electron diffraction, scanning tunneling microscopy, and density - functional calculations.

Others, however, think the chemical change can be explained in a more conventional picture, in which the electrons hop from atom to atom on the DNA rather than tunneling down the helix in one step.

Three - dimensional image using scanning tunneling electron microscopy of electrons on the surface of a Weyl semi-metal, a kind of crystal with unusual conducting and insulating properties.

That would put his tabletop device nearly on a level with the Stanford Linear Accelerator, which pushes particles to 50 billion electron volts in a 2 - mile - long tunnel.

17 Not to be outdone, Stanford scientists used scanning tunneling microscopy and holograms to write information within the interference patterns formed by electron waves on a copper sheet.

It will then test the device to see if it is possible to distinguish between the four types of nucleotides based on differences in a phenomenon called electron tunneling.

«The greater number of multiply charged clusters deposited on the surface built up a sufficient potential to allow the electrons from the surface to tunnel to the gold clusters, thereby reducing their charge state,» explained Johnson.

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.
