'Tuned' Graphene Points to Faster Chips 
Researchers at Rensselaer Polytechnic Institute have determined that the chemistry of the surface on which graphene is deposited plays a key role in shaping the material's conductive properties. Simulations show that when deposited on a surface treated with oxygen, graphene shows semiconducting properties, and when deposited on a material treated with hydrogen, it exhibits metallic properties.
