a Optical image of graphene/ITO hybrid electrode. Inset SEM image shows the surface structure of ITO bridges on left and right sides and the graphene film upon them. b Transmission spectra for PET substrate, ITO/PET film, graphene/ITO hybrid film on PET substrate, and the graphene/PET film. Inset photograph shows large domain of graphene upon ITO bridge on PET substrate. c AFM image of partial zone of graphene film; red arrow marks the distance of step area. Inset height change image of graphene edge marked in red arrow. d ITO edge step height measured by AFM image. Inset image shows the AFM image of ITO step and the marked distance of step area
