Researchers have built the world's smallest transistor - one atom thick and 10 atoms wide - out of a material that could one day replace silicon. The transistor, essentially an on/off switch, has been made using graphene, a two-dimensional material first discovered only four years ago. Graphene is a single layer of graphite, which is found in the humble pencil. The transistor is the key building block of microchips and the basis for almost all electronics. (source: news.bbc.co.uk)
