Abstract
In some aspects, a method for manufacturing graphene applied to grow graphene layers on an insulated surface of a work piece, includes: preparing a work piece; preparing a catalyst having a gasiform transition metal element; preparing a carbon feedstock; preparing hydrogen; mixing the carbon feedstock, the hydrogen and the catalyst over the work piece, the flow rate of the catalyst is between 4 sccm and 1,200 sccm; and warming the carbon feedstock, the hydrogen and the catalyst to the temperature between 200 degrees and 1,200 degrees centigrade, and maintaining the pressure inside the chamber between 1 mTorr and 800 Torr to make the catalyst source react with the carbon feedstock and the hydrogen so as to catalyze the decomposition of carbon feedstock to generate a plurality of carbon atoms, and the plurality of carbon atoms form the graphene layers directly on the insulated substrates of the work piece.
