Multilayered Graphene Electrode using One-Step Dry Transfer for Optoelectronics

In this study, multilayered graphene was easily transferred to the target substrate in one step usingthermal release tape. The transmittance of the transferred graphene according to the number of layers wasmeasured using a spectrophotometer. The sheet resistance was measured using a four-point probe system. Graphene formed using this transfer method showed almost the same electrical and optical properties asthat formed using the conventional poly (methyl methacrylate) transfer method. This method is suitablefor the mass production of graphene because of the short process time and easy large-area transfer. Inaddition, multilayered graphene can be transferred on various substrates without wetting problem usingthe one-step dry transfer method. In this work, this easy transfer method was used for dielectric substratessuch as glass, paper and polyethylene terephthalate, and a sheet resistance of ~240 ohm/sq was obtainedwith three-layer graphene. By fabricating organic solar cells, we verified the feasibility of using this methodfor optoelectronic devices. KCI Citation Count: 8
