Think thin —
Scientists identify hundreds of atomically thin materials
Computer scan of existing databases spits out materials that are only atoms thick.
Graphene may seem like a modern wonder-material, but it has been with us for ages in the form of graphite. Graphene is a sheet of carbon atoms bonded to each other, just one atom thick; graphite is just an agglomeration of these sheets layered on top of each other. To study graphene, however, it took someone clever to devise a way of peeling single layers off from this agglomeration (the secret turned out to be a piece of tape).
