Transistors are tiny components that can turn electrical signals on and off at incredible speeds. In this video, you'll learn how transistors act as switches and amplifiers, forming the foundation of ...

PORTLAND, Ore. — Expensive optical-to-electronic-to-optical converters are needed to switch photonic signals. Now, researchers have demonstrated an excitonic transistor that can perform the operation ...

Engineers are starting to build hardware that does not just run artificial intelligence, it behaves like a primitive form of ...

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, ...

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 ...

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 ...

Researchers have reported a black phosphorus transistor that can be used as an alternative ultra-low power switch. A research team developed a thickness-controlled black phosphorous tunnel ...

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 ...
