Graphene in the Wall Street Journal
The Wall Street Journal just posted a great article on the potential of graphene.
One factor holding graphene back is cost. Some U.S. vendors are selling a layer of graphene on copper foil for about $60 a square inch. "It needs to be around one dollar per square inch for high-end electronic applications such as fast transistors, and for less than 10 cents per square inch for touch screen displays," estimates Kenneth Teo, a director at the Cambridge unit of Germany's Aixtron SE that makes machines to produce graphene.Scaling up production is the next step towards a graphene world.
