A touch-screen with transparent electrodes made from graphene — single layers of carbon atoms — could be thinner, cheaper and more durable than today's devices that use indium tin oxide. But it has proved hard to manufacture these transparent films efficiently on a large scale.
Now Byung Hee Hong, Jong-Hyun Ahn at Sungkyunkwan University in Suwon, South Korea, and their colleagues have made such films (pictured) using a scalable industrial manufacturing process and incorporated them into a touch screen. They created 30-inch graphene films by depositing carbon atoms onto copper, which is later etched away. R.V.N.
