NOVELTY - The present invention relates to a method of diamond nucleation, comprising the following steps: providing a substrate and forming a graphene layer on a surface of the substrate; providing a reaction chamber and disposing the substrate in the reaction chamber; providing a gas mixture in the reaction chamber, wherein the gas mixture includes a carbon-containing gas; and forming a plasma in the reaction chamber to cause the carbon-containing gas to react and form a plurality of nuclei on the surface of the graphene layer. The structure formed by this method comprises a substrate; a graphene layer disposed on the substrate; and a plurality of diamond particles formed on the graphene layer.
