75 years ago this month, research scientists working at Bell Labs first created, then unveiled to the world a new device—the point contact transistor. Some call it the greatest invention of the 20th ...

Probably the most important invention of the 2oth Century was the transistor. The first point contact transistor shown below was made at Bell Laboratories. The workbench of John Bardeen and Walter ...

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 ...

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...

Building things in a lab is easy, at least when compared to scaling up for mass production. That’s why there are so many articles about fusion being right around the corner, or battery technology that ...

What Is A Single Electron Transistor? A single electron transistor (SET) is a transistor that operates on the principles of quantum mechanics and utilises the behaviour of single electrons. It differs ...

The new type of transistor, known as the "cryo-CMOS transistor," is optimized to operate at temperatures under 1 K and emit near-zero heat. When you purchase through links on our site, we may earn an ...
