Abstract :

In recent years, the new material graphene is at the center of synthesis of free standing two-dimensional nanostructures that provide a development of new technologies. The progress in the development of graphene devices is future promising and they are now considered as an option for the current Si-based electronics because of its unique properties. The most promising characteristic of graphene is its ability to be further functionalized based on the desired way. Although there are well-established methods to further functionalize the graphene sheets such as introducing a dopant atom or different level of defect structures, here we introduce a new and convenient way to change the properties of graphene by using different polymers which interact with CVD graphene during the transfer process. Additionally, Raman Spectroscopy is used for characterization of large area single layer graphene. By monitoring the variations of the wavenumber in G and 2D, we extract the doping properties in the graphene layer which shows different characteristics for different type of polymers.
