Figuring out certain aspects of a material's electron structure can take a lot out of a computer—up to a million CPU hours, in fact. A team of Yale researchers, though, are using a type of artificial ...

In a unique experiment, researchers have clocked how long it takes for an electron to be emitted from an atom. The result is .00000000000000002 seconds, or 20 billionths of a billionth of a second.

We can now detect single electrons with the resolution of a few trillionths of a second, and this could prove essential for building a new generation of quantum electronic devices. Traditional ...
