Princeton researchers have demonstrated a new way of making controllable "quantum wires" in the presence of a magnetic field. The researchers detected channels of conducting electrons that form ...

The presence of impurities or defects, also known as disorder, in a metal could hinder the flow of free electrons. Beyond a critical value, such disorder could completely stop electron flow, turning ...

Electrons flow through most materials more like a gas than a fluid, meaning they don’t interact much with one another. It was long hypothesized that electrons could flow like a fluid, but only recent ...

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 ...

Chestnut Hill, Mass (9/6/2021) -- A team of researchers from Boston College has created a new metallic specimen where the motion of electrons flows in the same way water flows in a pipe -- ...

RIKEN physicists have fabricated a nanoscale ‘heat engine’ that uses a property of electrons known as spin as the effective working medium 1. It is promising for exploring the development of ...
