Growing graphene without the mess

A conceptual illustration of an array of single atom-thick graphene transistors. Graphene is often hailed as potentially supplanting silicon in electronics, with its remarkable strength, despite its one atom-thick sheets, and its off-the-charts electrical properties. Researchers are experimenting with growing full-scale, four-inch graphene wafers. (Credit: Shivank Garg)
