In this lesson, students search for transistor-based devices at school. They use the results of their search to explain the significance of the transistor in their lives. A transistor is a tiny device ...

There was no doubt about it, point-contact transistors were fidgety. The transistors being made by Bell just didn't work the same way twice, and on top of that, they were noisy. While one lab at Bell ...

Confined molecules inside carbon nanotubes polarize under gate voltage, creating transistors with three stable logic states from a single material system.

The future began 75 years ago this week with the invention of something small that’s considered the most manufactured item in human history. Odds are, you are surrounded by them right now. The ...

A huge portion of electronic devices that are discarded at the end of their lives are never recycled, and a big part of the problem is the difficulty in separating out and recovering the valuable ...

THANKS to the exponential power of Moore’s law, the electronic components that run modern computers vastly outnumber all the leaves on the Earth’s trees. Chris Mack, a chipmaking expert, working from ...

When a Hackaday article proclaims that its subject is a book you should read, you might imagine that we would be talking of a seminal text known only by its authors’ names. Horowitz and Hill, perhaps, ...
