Graphene transistor held by tweezers in the palm of a person's hand. Graphene is composed of a single layer of carbon atoms that is both flexible and very strong. It conducts electrons faster than silicon and could one day replace silicon in applications such as nanometre (billionths of a metre) sized electronics, cheap and efficient solar panels, transparent window coatings and miniature sensing technologies.Graphene was discovered by Andre Geim in 2004.
