Silicon chip speed record broken on a lead-coated track

A “racetrack” developed by Pohang University of Science and Technology in South Korea has set a theoretical new record for silicon chips: 20 times faster. It uses an atom-thick layer of lead added to the surface of a silicon block.

The development could allow silicon to compete with graphene, a form of carbon.
