Electricity is nothing but the flow of electrons through substances. Some substances are noted for being very good “conductors”–that is, they allow electrons to flow through them quite readily–and ...

Physicists are familiar with persistent currents in superconductors – in which electrons can flow forever, unhindered by resistance. But even the best normal conductors such as copper or gold have ...

In an electrical conductor, electrons flow in quantum channels, much like cars in highway lanes. Similar to highway lanes, each electronic channel has a finite capacity to conduct electrons, limited ...

Electron hydrodynamics in three-dimensional materials remained much more elusive because of a fundamental behavior of electrons in conductors known as screening.

In an insulator, electrons are largely stuck in one place, while in a conductor, the electrons flow freely.

Physicists have directly measured, for the first time at nanometer resolution, the fluid-like flow of electrons in graphene. The results have applications in developing new, low-resistance ...

A recently developed theory, however, suggests that under certain conditions, a coupled electron–phonon liquid can form in which the electrons transition from a diffusive (particle-like) flow to a ...

How fast do electrons drift through a conductor? The speed of light? Actually, no — remember, drift velocity is the average speed of an individual electron, not the speed of the electric current.

In essence, normal Fermi liquid type metals have too many opportunities for electrons (as quasiparticles) to be knocked off track as they flow through, leading to the production of heat.

Strange metals defy the 60-year-old understanding of electric current as a flow of discrete charges. (Nanowerk News) We all learned that electricity is caused by electrons moving in a metal. Each ...

Electrons in graphene can act like a perfect fluid, defying established physical laws. This finding advances both fundamental ...

Researchers from the Indian Institute of Science’s Department of Physics, together with researchers from Japan's National ...
