Georgia Institute of Technology researchers have described a way of making graphene that preserves the material's conductive properties, an early step toward graphenesilicon electronicsFor years researchers have held out hope that graphene would be the material to pick up the mantle in the electronics industry when silicon hits its limits as the material of choice for making devices smaller, faster and cheaper. Yet, turning graphene's promise into a reality has been difficult to say the least, in part because of the inherent difficulty of working with a substance one atom thick.
