Seven Atom Transistor

The transistor is the foundation for the semiconductor industry and all of our modern electronic miracles. The ability to shrink transistors has led to cheaper and faster electronic devices, as well as solid state storage and digital photography.

Australian researchers have now created the world's smallest transistor, consisting of only seven atoms arranged into a single silicon crystal. It is fully functional and can regulate and control the flow of electrical current, despite being only 4nm across.
