Large-area graphene film could be synthesized on a copper foil using low pressure chemical vapor deposition (LPCVD) method. Graphene is a promising material to revolutionize future electronics and membrane separation technology. So, growth of a defect-free graphene film is the need of the hour. Sometimes during the graphene growth using LPCVD technique, a high density of contamination which make graphene absolutely defective are produced in the its lattice. In this research, we have managed to synthesize a contamination-free graphene film on the copper foil surface using LPCVD process. We discovered the nature and source of the contamination and then prevents their production through controlling the operating conditions of the CVD process. These findings could pave the way of synthesizing a defect-free graphene film and also make the use of graphene in different applications feasible.
