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

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 ...

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 ...

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 ...

A condition long considered to be unfavorable to electrical conduction in semiconductor materials may actually be beneficial in 2D semiconductors, according to new findings by UC Santa Barbara ...

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 ...
