Devices based on surface electrons in topological insulators are keenly anticipated, but singling these electrons out amid abundant bulk electrons poses a formidable challenge. Inspiration from ...

When two different substances are brought together, the electrons can move randomly. When the substances are separated, static electricity occurs if the balance of electrons is disturbed.

A trio of scientists won the Nobel Prize in physics for managing to do something that had always eluded humankind: Spotting electrons zipping around in an atom.

Electrical current is a stream of charged elementary particles. In semiconductor devices, ballistic electrons move at high speeds, making it difficult to address them individually. A controlled ...

But, because of the massive positive charge of the nucleus, some of seborgium's electrons are moving rather quickly—about 80 percent of the speed of light.

Scientists at Cambridge University have shown an amazing degree of control over the most fundamental aspect of an electronic circuit, how electrons move from one place to another.

With electrons that move with such ease, Ga2O3 could be a promising material for applications such as high-frequency communication systems and energy-efficient power electronics.

An electric current is a flow of charged particles. A source of energy, such as a cell or battery, is required to make the free electrons move in one direction. Electrons are negatively charged ...
