A transistor is a tiny but powerful electronic component that acts like a switch or an amplifier. It is made from a semiconductor material, usually silicon, and has three legs for connection to ...

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 . . .

Transistors act as electrical switches. In the on position, which represents the “1” of binary digital information, a designated amount of current flows from one side of a semiconductor to the other.

Perovskites have received a lot of attention as semiconductor materials for solar cells because they’re efficient, inexpensive, and easy to make. But designing transistors, the fundamental component ...

An electrical switch made from conductive wood could become a building block for future electronic devices embedded within living trees and other plants. “There is an emerging research field called ...
