Controllable electron flow in quantum wires Date: February 6, 2019 Source: Princeton University Summary: Scientist have found they can turn on and off the flow of current in a bismuth crystal ...

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.

In this material, the team etched a narrow channel with a circular chamber on either side, then ran a current through it and measured electron flow. In standard materials like gold, ...

They’ve essentially toggled the electron highway signs with an external magnetic field. This elegant control over band asymmetry might lead to low-power, high-speed data storage based on ...

He asked which way does *current* flow. And current has a definition in physics, and it’s a vector – so there’s absolutely, 100% a correct answer: in a conductor, current is just the ...

The colorful graph represents how the electrical current changes at different temperatures when voltage is applied. The background illustration depicts the thin layer spread over two electrode ...

Liquid-like electron flow. Boston College researchers reveal a novel metal where electrons flow with fluid-like dynamics. A team of researchers from Boston College has created a new metallic specimen ...

First practical application of viscous electron flow realizes terahertz photoconductivity in graphene. ... mapped onto the streamlines of electrical current flowing through the PC exposed to THz ...

Recent research suggested that hydrodynamic electron flow in 3D conductors was possible, but exactly how it happened or how to observe it remained unknown. Until now.

A team has 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.
