Graphene Synthesis and Characterization

: Here is reported graphene synthesis by two methods, Chemical Vapor Deposition (CVD) using Acetylene as a Carbon source onto copper substrates, and the exfoliation of graphite (chemical and electrochemical). These methods have a great importance for applications in devices, because can be properly scaled to industrial level. It was studied the experimental parameters involved in the growth of graphene. By Raman spectroscopy was made the characterization of material obtained. CVD method allow to grow single- and few-layer graphene on copper. On the other hand, the exfoliation method produced multi-layer graphene flackes.
