Micro Raman investigation of graphene synthesized by atmospheric pressure CVD on copper foil from decane
Get PDFIn this article we present the results of micro-Raman studies of graphene grown on copper foil surface by atmospheric pressure
CVD using decane as precursor, nitrogen as carrier gas with zero flow of hydrogen. Analysis of Raman spectroscopy data
showed that film contains spots with single layer thick graphene. We observed significant blue shift of 2D and G bands positions
for mono-atomically thick graphene on copper foil. Following literature we relate this shift to the strain induced by the presence
of copper substrate. Moreover, we observed changes in the defectiveness of graphene layers after the transfer, which was related
to the appearance of chemically-induced defects and defects induced by changes in the mechanical strain
