Which way does electricity flow through a vehicle’s electrical system? From positive to negative, or from negative to positive? Depending on your viewpoint, it can flow either way. When most people ...

A group of scientists has created a quantum material where electricity can flow without losing energy as heat. Until now, this was only seen in ...

Strange metals defy the 60-year-old understanding of electric current as a flow of discrete charges. (Nanowerk News) We all learned that electricity is caused by electrons moving in a metal. Each ...

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 ...

Scientists have pulled off a feat long considered out of reach: getting light to mimic the famous quantum Hall effect. In ...

A team of US researchers has unveiled a device that can conduct electricity along its fractionally charged edges without losing energy to heat. Described in Nature Physics, the work, led by Xiaodong ...

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 ...

A diode is a semiconductor device that allows electrical current to flow in one direction while blocking it in the other.

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

In a strange metal (translucent box), electrons (blue marbles) lose their individuality and melt into a featureless, liquid-like stream. We all learned that electricity is caused by electrons moving ...
