If you want an electrical current to flow around a normal metal ring you have to supply enough energy to overcome the metal’s resistance – right? Not always, according to physicists in the US and ...

In this diagram the upper-left end of the platinum film (shown in light blue) is hotter than the lower-right end. This causes electrons to flow from hot to cold. The spin Nernst effect is shown as ...

Physicists at the University of Wisconsin-Madison have directly measured the fluid-like flow of electrons in graphene at nanometer resolution for the first time. The results appear in the journal ...

Physicists report new insights into the behavior of electrons on the surface of a topological insulator, a class of material with unique properties that challenge some of the oldest laws of physics.

Since electrons are so small and one electron will not have much of an effect anywhere, it is more useful to refer to packages of electrons. One coulomb of charge is a package equivalent to ...

A condition long considered to be unfavorable to electrical conduction in semiconductor materials may actually be beneficial in 2D semiconductors, according to new findings by UC Santa Barbara ...
