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 ...

Duke engineers show how a common device architecture used to test 2D transistors overstates their performance prospects in real-world devices.

A transistor is a key component in electronics, often used as a switch or to amplify a signal from a sensor. NPN (negative-positive-negative) transistors are the most used transistor. An illustration ...

IBM has created graphene transistors that leave silicon ones in the dust. The prototype devices, made from atom-thick sheets of carbon, operate at 100 gigahertz–meaning they can switch on and off 100 ...

Electronic components built from single molecules using chemical synthesis could pave the way for smaller, faster and more green and sustainable electronic devices. Now for the first time, a ...

(Nanowerk Spotlight) Probably the hottest new material system being researched at the moment, graphene consists of just a single atomic layer of carbon atoms bound into crystal lattice. This carbon ...

I'm playing with setting up some simple circuits, but none of my transistors seem to work. My latest attempt at making them do *something* goes as follows: I hooked up a 180 ohm resistor to the ...
