If there's a rock star in the world of materials, it's graphene: single-atom–thick sheets of carbon prized for its off-the-charts ability to conduct electrons and for being all but transparent. Those qualities make graphene a tantalizing alternative for use as a transparent conductor. But the material has been tough to manufacture in anything larger than flakes a few centimeters across. Now researchers have managed to create much larger rectangular sheets of graphene. (source: news.sciencemag.org)
