The components in a home audio/video system are pretty complicated to anyone without a good understanding of electronics; but wire–good, old-fashioned wire–is something we can all understand. It’s ...

The electrical resistance of a metal is caused by electrons being scattered from impurities in the material’s atomic lattice or from lattice vibrations called phonons. However, it is not affected by ...

If you think about an asylum, there are two kinds of people in it: staff and patients. We aren’t sure which one [Nick Lucid] is in the latest The Science Asylum video that tries to answer the question ...

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 ...

Ballistic electrons are among the most fascinating phenomena in modern quantum materials. Unlike ordinary electrons, they do ...

This video explains how diodes function as directional components in electronic circuits. Diodes allow current to flow in ...

A new type of switch sends electrons propagating in opposite directions along the same paths – without ever colliding with each other. The switch works by controlling the presence of so-called ...

(NewsNation) — Physicists at MIT have found a way to observe electrons in some exotic materials that appear to flow without resistance. The discovery could lead to the invention of superefficient ...

Physicists at the University of Wisconsin-Madison directly measured, for the first time at nanometer resolution, the fluid-like flow of electrons in graphene. The results, which will appear in the ...
