Raman Mapping Analysis of Graphene Transferred by Multiple Techniques
POSTER
Abstract
Graphene transfer utilizing polymer assisted transfer technique leaves impurities. These impurities affect both electrical and structural properties of graphene. Determining the quality of the sample is important for use in later device applications. Extracting full width half maximum (FWHM), center location, and intensity of Raman peaks offers insight into how a sample has been changed from the transfer process. Using a free Python package and easily accessible libraries it is possible to extract and visualize the properties of graphene samples. By analyzing Raman data, we have optimized the polymer assisted graphene transfer utilizing various polymers and a process for cleaning the sample using a Soxhlet apparatus.
