Doping stability and opto-electronic performance of chemical vapour deposited graphene for plastic electronic applications

We report the transfer of chemical vapour deposited graphene to polymer supports by utilizing thermal and ultraviolet (UV) laminate techniques. The time-dependent evolution of the opto-electronic performance was assessed following exposure to five kinds of common dopants, FeCl₃, SnCl₂ IrCl₃, RhCl₃, and AuCl₃. In general, the doping markedly reduced the sheet resistance, with the exception of IrCl3 doping, thereby offering a means of realising viable transparent flexible conductors that can be used in the production of OLEDs and other devices.
