Regular on/off switches rely on fingers and springs to bring bits of wire together or apart. When the wires touch, electrons flow from one to the other, and your computer/nightlight/sock warmer is on.

Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

Most field-effect transistors work by tuning the energy of a charge channel relative to a charge source. While the transistor is turning on, charges from the source need to overcome a barrier to enter ...

A transistor is a tiny but powerful electronic component that acts like a switch or an amplifier. It is made from a semiconductor material, usually silicon, and has three legs for connection to ...

How Do Transistors Work? At its core, a transistor is an electronic gatekeeper. It controls the flow of electric current through a semiconductor material. Most transistors have three terminals, often ...
