In this thesis, mono-to-multilayer graphene for transparent electrode applications was synthesized by Atmospheric Pressure Chemical Vapor Deposition (APCVD) and the key factors that determine the electrical and optical properties of the graphene were isolated. This work involves optimizing APCVD conditions to grow the best quality graphene for transparent electrode applications as well as explaining the underlying mechanisms behind APCVD. The effects of methane and hydrogen in the growth step were studied along with the impact of the annealing step. Growth without hydrogen was also investigated. Sheet resistance, transmittance, and mobility data with carrier concentration information were obtained and analyzed for each growth condition. This work explored a large set of APCVD conditions with focus towards the electrical and optical properties; therefore it will be greatly beneficial for researchers who seek to the high quality graphene for the transparent electrodes and other electronic applications.
