An NPN transistor is a type of bipolar junction transistor (BJT) that consists of three layers of semiconductor material. These layers are arranged with an N-type emitter, a P-type base, and an N-type ...

If computer chips could be built from semiconductors just one atom thick, they could pack far more transistors into a smaller ...

For decades, silicon transistors have driven computational power, and scientists have devoted much of their time to making ...

Transistors are small, versatile semiconductor devices designed to switch or amplify electronic signals and power. Almost all electronic devices today contain one or more transistors. Some transistors ...

The ISL73096EH is a radiation hardened ultra high frequency NPN/PNP transistor array. It contains three NPN transistors and two PNP transistors on a common substrate. The device covers all of the ...

Shrinking silicon transistors have reached their physical limits, but a team from the University of Tokyo is rewriting the rules. They've created a cutting-edge transistor using gallium-doped indium ...

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 ...

There was no doubt about it, point-contact transistors were fidgety. The transistors being made by Bell just didn't work the same way twice, and on top of that, they were noisy. While one lab at Bell ...
