Abstract

Abstract Few layered graphene is synthesized on Cu foil by thermal chemical vapor deposition. We have investigated the effect of temperature and catalyst’s thickness on graphene domain length and number. The synthesized graphene was characterized using Raman spectroscopy and scanning electron microscopy. Raman spectroscopy results show that D-peak intensity increases with an increasing temperature which revealing that some defects have been generated during synthesis on Cu surface synthesis at higher temperature. It also has been observed that increasing in temperatures result in more intense 2D peaks. Although for further rise in temperature, although the number of graphene domain increases and the graphene domain length reduces. Our results provide important guidance toward the synthesis of high quality graphene films.
