Further, by being able to precisely measure electron density, it will now be possible to clarify through computer simulation the important behaviors of active ion species that play important roles in their interaction with living organisms and materials hazardous to the environment.
As the electron density outside the quantum point contact is increased, the material becomes superconducting and the transmission of Cooper pairs — the particles that comprise a superconducting current — through the constriction was also studied in this work.
«By modelling experimental synchrotron data and comparing it with density functional theory calculations, we revealed surprising information about the nature of the electron sharing between layers in these materials.»
The combination of the high electron density and potent electron interactions are not seen in other materials and the quantum regime enforced by the tight passageway, might here be engendering some new kind of electron transport.
«Normally in a metal like silver or copper or gold, the density of electrons in that metal is fixed; it's just a property of the material,» Atwater says.
By adjusting various parameters — such as the density of conduction electrons in the material or the strength of the DC electric field — it is possible to tune the cutoff wavenumber and, consequently, the frequency of the resulting terahertz radiation.
Because of the huge mass / density difference of the two materials, this pairing provides maximum contrast in the electron microscope and delineation was easily distinguishable between the particle core and shell.
