Abstract
The application of graphene films as transparent conductive electrodes has shown promising results recently. In this paper, we report a simple, scalable, and economic method for preparation of graphene using annealing of amorphous carbon film deposited on Co/quartz substrate and successive transfer onto quartz substrates toward transparent conductive film application. In this regard electron-beam technique is used for deposition of Co thin film on quartz as a synthetic catalyst and an amorphous carbon film is deposited by sputtering technique. Also, we demonstrate the application of transferred graphene on quartz substrate as bottom plate in the fabrication of 4-resistive touch screen. The transferred graphene films on quartz substrate show sheet resistance of 2 kΩ/sq, with 80% optical transparency in visible wavelength range. The resolution of touch screen was 0.75cm.
