Without transistors the modern world would simply not exist. But how do they work, and how do modern, atomic sized versions compare with the originals? The word "transitor" has become almost invisible ...

This video explains how transistors work as switches and amplifiers in electronic circuits. Transistors control the flow of current and enable signal processing in everything from small devices to ...

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 ...

With transistors and logic gates as our basic building blocks, we can begin to construct the actual circuits that make up computer memory. One of the simplest memory circuits is the AND gate, which ...

Perovskites have received a lot of attention as semiconductor materials for solar cells because they’re efficient, inexpensive, and easy to make. But designing transistors, the fundamental component ...

This is the third installment in our CPU design series. In Part 1, we covered computer architecture and how a processor works at a high level. Part 2 explored the design and implementation of ...

One of the joys of writing up the entries for the 2025 Component Abuse Challenge has come in finding all the different alternative uses for the humble transistor. This building block of all modern ...
