In this research, the electrochemical delamination (ECD) and chemical metal etching (CME) techniques were performed to transfer the chemical vapor deposition (CVD) grown graphene onto glass and SiO2 substrates. Principally, graphene was grown on a copper substrate by chemical vapor deposition (CVD) under specified conditions. Atomic force microscopy (AFM), Raman spectroscopy and X-ray Diffraction (XRD) were employed to investigate the morphological aspects and qualities of transferred graphene

The Raman spectra analyses result revealed that Raman-bands positions of the transferred graphene could be shifted by the using various transfer methods or substrate. However, the thickness and the visible light transparencies of the transferred graphene samples were almost similar. The graphene sample transferred via ECD has portrayed lowest D to G-bands ratio (ID/IG) which indicates better graphene.
