Abstract
AbstractHere we report the data on the few layer graphene films grown by a chemical vapour deposition on nickel foils and transferred onto desirable substrates for different applications. The experimental conditions have been optimized to prepare a really single graphene layer. A strong influence of the growth conditions onto the number of graphene layers has been revealed. Raman spectroscopy was used to confirm the formation of the single graphene layer with a little amount of defects. To estimate a transmittance of graphene films the optical absorption spectra have been measured. A number of graphene layers in different samples has been estimated on the base of an optical absorbance of a monolayer graphene (2.3% of the incident light intensity).
