초록
Recently, mono-layer and few layer graphene films grown by chemical vapor deposition (CVD) using metal substrate as a catalyst have attracted tremendous attention for the last few years. Copper (Cu) has been extensively used as a growth catalytic substrate due to its very low carbon solubility, which is thought to be responsible for the self-limiting precipitation growth and surface decomposition of carbon-containing molecules. Graphene films were synthesized on two types of catalytic substrates, electro-plating and rolling Cu foil, by chemical vapor deposition. Graphene film grown on various Cu foils was analyzed by Raman spectroscopy and scanning electron microscopy (SEM), with the aim of assessing their characteristics and finding the optimum catalyst conditions.
