Samsung appears to have stumbled across the holy grail of commercial graphene production: A new technique that can grow high-quality single-crystal graphene on silicon wafers -- graphene that is suitable for the production of graphene field-effect transistors (GFETs) -- and afterward, once the graphene has been peeled off, the silicon wafers can even be reused! Samsung is dressing this up as a breakthrough for flexible, wearable computers -- which is fair enough, given the company's recent focus on curved smartphones and watches.
