This report introduces the electromagnetic absorption of the catalyst as anovel knob in optimizing chemical vapor deposition of graphene. A chromium filminitially deposited at one side of a catalyst copper foil absorbs radiativethermal energy several times higher than the plain copper foil and migrates tothe other side of the foil in the form of microscale grains. The processinvolves local melting of the copper which together with the increasedoperation temperature, improves the crystalline quality of growing graphene.Local melting of copper replaces the otherwise-necessary annealing process;dramatically lowering the process duration and costs. Now a continuous graphenefilm can be grown in only five minutes, nominating the protocol as the shortestever reported. The observations reported in this manuscript boost the generalknowledge about metal mixture, additional to promoting graphene growth scienceand technology.
