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 ...

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 ...

The transistor is probably the most important invention in electronic engineering and the basis for nearly all integrated circuits (ICs). The transistor is a three-terminal electronic device that can ...

WEST LAFAYETTE, Ind. - A simulation of electrical current moving through a futuristic electronic transistor has been modeled atom-by-atom in less than 15 minutes by Purdue University researchers. The ...

In the beginning, there was the point-contact transistor. This was the very first transistor ever made, built by Walter Brattain with the help of John Bardeen. It was made of two gold foil contacts ...
