Transistors are tiny electronic components that act as switches and amplifiers, and they dwell at the heart of modern technology. In simple terms, a transistor can turn a flow of electricity on or off ...

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 . . .

A single electron makes the difference between “on” and “off” for a new transistor made from a single carbon nanotube, whose minute size and low-energy requirements should make it an ideal device for ...

With the development of carbon nanotubes and graphene, scientists were given an entirely new collection of materials to work with: sheets and tubes that could be consistently made with thicknesses ...

A new study represents a significant advance in topological transistors and beyond-CMOS electronics. First time that the topological state in a topological insulator has been switched on and off using ...

1. What is a semiconductor? Generally speaking, the term semiconductor refers to a material—like silicon—that can conduct electricity much better than an insulator such as glass, but not as well as ...

Transistors are needed wherever current flows, and they are an indispensable component of virtually all electronic switches. In the field of power electronics, transistors are used to switch large ...
