  • Mass-Producing Graphene | American Scientist

    This work was inspired by an earlier paper, which fused CVD with epitaxial growth to improve the graphene yield. It seems that somehow the combination of these two processes creates a product that is leagues better than either isolated method. If time shows that this combination turns out to be repeatable and economical, it could set the stage for graphene’s everyday importance to skyrocketОнлайн-запрос
