A memory effect that is crucial in electronics has been seen for the first time in a cloud of ultracold atoms. The phenomenon represents a milestone in the emerging field of ‘atomtronics’, which seeks ...

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

In the first demonstration of its kind, researchers have controlled the spin of electrons using a ballistic technique -- bouncing electrons through a microscopic channel of precisely constructed, ...

Electricity powers our lives, including our cars, phones, computers, and more, through the movement of electrons within a circuit. While we can't see these electrons, electric currents moving through ...

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 nano-scale electronic circuits, the phenomenon of quantum interference between electrons can lead to states where electrons appear to split. Professor Mitchell said, "In a nanoelectronic circuit, ...

Artist’s impression of the quantum spin Hall effect in a graphene-based spintronic device, integrated in a chip. The blue and red spheres are spin-up and spin-down electrons traveling along the edge ...

A river made of graphene with the electrons flowing like water. Courtesy: Ryan Allen and Peter Allen, Second Bay Studios Electrons can behave like a viscous liquid as they travel through a conducting ...

In Part 1 of the Electronics for Kids series, we looked at LEDs; in Part 2, we explored capacitors; and in Part 3, we took an in-depth look at electrical measurements. In this article, we will focus ...
