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 ...

Scientist have found they can turn on and off the flow of current in a bismuth crystal subjected to a high magnetic field, making a new type of controllable quantum wire. Princeton researchers have ...

Coulomb blockade is a phenomenon in which the flow of electrons through a nanostructure, such as a quantum dot or a single-electron transistor, is restricted due to the electrostatic repulsion between ...

An international research team has successfully developed technology that’s able to control and measure spin current in the same way as electrical current. The team of physicists hails from the ...

A team of researchers has developed a theory to explain how hydrodynamic electron flow could occur in 3D materials and observed it for the first time using a new imaging technique. Electrons flow ...

Scientists identify two sound-driven mechanisms for generating orbital currents, merging acoustics with cutting-edge electron ...

The fluid-like movement of electrons in graphene was directly observed by physicists at the University of Wisconsin-Madison for the first time at a nanometer resolution. The findings have the ...

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 ...
