柔性光伏和有机发光器件的效率在很大程度上依赖于柔性和透明导体的可用性，这些导体至少具有与氧化铟锡相似的工作功能。在这里，我们首次研究了化学气相沉积在镍上生长的大面积（高达9 cm2） FeCl3插层石墨烯的功函数，并证明其值高达5.1 eV。插入后，每层石墨烯的电荷密度达到5⋅1013±5⋅1012 cm−2，使该材料成为研究电信行业感兴趣的红外波长光谱中的等离子体激发的有吸引力的平台。最后，我们展示了这种材料在聚萘二甲酸乙二醇酯衬底透明电路中的柔性电子器件的潜力。
The efficiency of flexible photovoltaic and organic light emitting devices is heavily dependent on the availability of flexible and transparent conductors with at least a similar workfunction to that of Indium Tin Oxide. Here we present the first study of the work function of large area (up to 9 cm2) FeCl3 intercalated graphene grown by chemical vapour deposition on Nickel, and demonstrate values as large as 5.1 eV. Upon intercalation, a charge density per graphene layer of 5 ⋅ 1013 ± 5 ⋅ 1012 cm−2 is attained, making this material an attractive platform for the study of plasmonic excitations in the infrared wavelength spectrum of interest to the telecommunication industry. Finally, we demonstrate the potential of this material for flexible electronics in a transparent circuit on a polyethylene naphthalate substrate.
