The handedness or “chirality” of electrons affects how current flows in graphene transistors, according to new work done by researchers in the UK and Russia. The team’s findings could help to make ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

What Is A Semiconductor Gate? The gate electrode is a thin film of a conductive material deposited on top of an insulator layer in a transistor. The gate sits above a channel formed in the main body ...

This Design Idea is a two-wire current regulator that strikes a good balance between performance and parts count. Employing three transistors, three resistors, and one LED, it achieves good regulation ...

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 ...

Graphene has already brought us the world's smallest transistor – twice – and now the one atom thick form of carbon that recently won its discoverers the Nobel Prize has been used to create a ...

In 1947, Shockley, Brattain and Bardeen were investigating the field effect transistor but lead them into inventing the bipolar transistor instead. In 1952, the field effect transistor of Shockley was ...
