Atom-sized transistor is world's smallest


Made from graphene, scientists in the UK have created the world’s smallest transistor. Size? Oh, say, about the size of an atom.

The transistor, which could totally change the way electronics are made, is just one atom thick and 10 atoms wide. Again, it’s made from graphene, which, apparently, is a significantly better conductor of electricity than silicon. “We believe we can increase this mobility of electron flow 10-fold.”

So yes, pretty small. The transistor is actually embedded somewhere in the device to the right. Obviously you can’t see it—it’s too small!
