碩士 === 國立中正大學 === 光機電整合工程研究所 === 101 === In this study, we established a rapid analysis system for few-layer graphene films. First, we create the database for different layers of graphene films spectral characteristics on SiO2(300nm)/Si substrate and the glass substrate, respectively. This database was created by the image capture system (ICS) and multi-spectral imaging technology. Finally, we use principal component score plot to create a database to determine different layers on different substrates. When the unknown sample need to identify, we will enter it into database to analysis. Finally, we use different colors to mark the position of different layers. In this study, we analysis and marked graphene layers on the SiO2(300nm) / Si substrate and the glass substrate, successfully.
