U. of Manchester Unveils Smallest Graphene Transistor

Researchers from the University of Manchester have created the world’s smallest transistor.

The transistor, made of graphene (a carbon-based material), measures one atom thick and ten atoms across. The same team developed a slightly larger transistor last year that was 50 atoms across.

The development stems out of the limitations of silicon, which becomes less effective on microchips at a nanoscale. —Hurley Goodall
