Rapid Microwave Synthesis of Graphene Directly on <i>h</i>-BN with Excellent Heat Dissipation Performance

Abstract

We report a new rapid household microwave method to successfully grow graphene on h-BN flakes without using any catalysts. We obtained a novel uniform multilevel matrix of vertical graphene sheets on h-BN flakes. The unique structure possessed outstanding electron conductivity and thermal properties (29.1 W m(-1) K(-1)).
