IBM researchers have demonstrated a graphene circuit which integrates all circuit components onto a single wafer made of silicon carbide. Graphene is a mesh of carbon atoms that's one atom thick. Integrating it monolithically -- meaning in one unit -- with other materials is a problem researchers have been grappling with since 2004, when the material's properties were first demonstrated. IBM announced the demonstration of its monolithically integrated graphene circuit in a paper published Friday in the journal Science.
