How Do Transistors Work? At its core, a transistor is an electronic gatekeeper. It controls the flow of electric current through a semiconductor material.

Home > Science What Is a Transistor, and How Does It Work? Join us for a deep dive into the tiny technology that powers the world.

The transistor was born in 1947 at Bell Labs in New Jersey. We’re looking into the culture of innovation that made it possible.

What does Nokia Bell Labs look like 75 years since the transistor’s invention? It’s responsible for the transistor, information theory, pioneering satellite work and more.

As Moore’s law turns 50, what does the future hold for the transistor? The future of Moore's law is uncertain, but there's still plenty of great tech on the horizon.
