Researchers have revived and improved a once-reliable technique to identify and count defects in transistors, the building blocks of modern electronic devices such as smartphones and computers.

With the right mix of materials, TFETs promise cooler, smaller, and more efficient circuits for everything from the Internet of Things to brain-inspired computers. But before they can leave the lab, ...

Shrinking chips are hitting a wall. Traditional transistors, the workhorses of modern electronics, are struggling to switch faster without guzzling power. A rival design, the tunnel field-effect ...
