Using DNA to assemble a transistor from graphene

DNA is the blueprint for life. Could it also become the template for making a new generation of computer chips based not on silicon, but on an experimental material known as graphene? That’s the theory behind a process that Stanford chemical engineering professor Zhenan Bao reveals in Nature Communications.

'Perfect' transistor built from a single atom

Physicists have created a working transistor using only a single phosphorus atom placed precisely in a silicon crystal.

Proton-based transistor could let machines communicate with humans

Materials scientists at the University of Washington have built a transistor that uses protons rather than electrons, in a breakthrough that could allow devices to communicate directly with living things.

Programmable nanoprocessor created

Harvard University scientists and the Mitre Corporation have  demonstrated the world's first programmable nanoprocessor.

IBM graphene chip outperforms silicon

IBM has developed the world's fastest graphene transistor, which outperforms traditional silicon.
