The two types of standard transistors are PNP and NPN which differs in circuit symbols. The layers of semiconductor material used to make the transistor are denoted by the letters. To keep a straight ...

The use of transistors for switching things ON and OFF is a key feature of proper hacking. The ability for bipolar transistors to turn things ON and OFF is one of the less known uses while transistors ...

This video explains how transistors work and how they are used to switch and amplify electrical signals in electronic circuits. Transistors are fundamental to all modern digital and analog systems.

A new material can withstand 'billions' of electrical cycles without wearing out — and scientists say it could transform electronics within 10 to 20 years. When you purchase through links on our site, ...

Fast switching: the Hybrid Photonics Labs at Skoltech where the new optical transistor was created. (Courtesy: Skoltech) A new optical transistor has been designed by researchers in Russia, ...

Why it matters: Silicon transistors are great, but just like any other object in the physical world, they are held back by a few limitations. The laws of physics put a bottleneck on performance and ...
