Abstract
On an industrial scale, it is still a great challenge for the researchers to develop clean and efficient method for the production of large area high quality graphene needed for various applications. Several growth and transfer related issues still need to find an answer. Here we report on the growth and transfer of uniform and continuous large-sized thin-films composed of single- and few-layered of graphene. The films were grown by chemical vapor deposition (CVD) on polycrystalline copper (Cu) foils at low pressure using ethanol and were transferred onto the desired substrates using a cyclododecane supporting layer. Structural and optical characterizations indicate that the graphene films are composed of single or few layers depending on the growth conditions and exhibit low defect density. The graphene films can be transferred onto arbitrary substrates with the help of a green transfer method based on an organic molecule, cyclododecane.
