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 ...

Researchers at MIT have observed “electron whirlpools” for the first time. The bizarre behavior arises when electricity flows as a fluid, which could make for more efficient electronics. Like water, ...

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 ...

The handedness or “chirality” of electrons affects how current flows in graphene transistors, according to new work done by researchers in the UK and Russia. The team’s findings could help to make ...

Electric current comes in many forms: current in a wire, flow of ions between the plates of a battery and between plates during electrolysis, as arcs, sparks, and so on. However, here on Hackaday we ...

A graphene-based “beam splitter” for electronic currents has been built by researchers in France, South Korea, and Japan. Created by Preden Roulleau at the University of Paris and colleagues, the ...

Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...
