Doping of Graphene Film for Transparent Conducting Film

We propose a method of doping graphene films in order to use in transparent conducting films. Graphene film was synthesis on copper film by chemical vapor deposition method (CVD) and transferred onto polyethylene terephthalate substrate. Phenylboronic acid acceptor and donors were used to promote graphene's electrical properties. The doping mechanism based on the modify valence band structure of graphene. The existence of the boron was verified based on Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM) images. The influence of doping on the electrical properties of graphene were measured by Four-probe measurement and sheet resistance was decreased up to 55%.
