If you are an EE you definitely know the answer to this, or at least you think you do. If you said positive to negative, you are wrong. Then you remember that current flow is a charge of electrons ...

Electric currents can be steered by coupling the flow of electrons and ions in films of gold nanoparticles coated with ionic ligands. The co-existence of ionic flow and electron flow has been observed ...

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 ...

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 ...

Key learning points Electrical charges What are free electrons? Cell polarity Conventional current direction Electrons orbit the nucleus. An atom has a neutral charge, because it contains the same ...

If you ever wished electrons would just behave, this one’s for you. A team from Tohoku, Osaka, and Manchester Universities has cracked open an interesting phenomenon in the chiral helimagnet α-EuP 3: ...

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 ...

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, ...

Physicists have now observed electron whirlpools. Theorists have long predicted electrons should exhibit this hallmark of fluid flow; the findings could inform the design of more efficient electronics ...

On a quest to discover new states of matter, a team of Princeton University scientists has found that electrons on the surface of specific materials act like miniature superheroes, relentlessly ...
