石墨烯只有一个原子厚，光学透明，化学惰性，是一种优秀的导体。这些特性似乎使这种材料成为需要导电但透明薄膜的各种光子器件中应用的优秀候选者。在这封信中，我们展示了具有石墨烯制成的电极的液晶器件，该器件显示出具有高对比度的优异性能。我们还讨论了石墨烯与常规使用的金属氧化物相比在低电阻率，高透明度和化学稳定性方面的优势。
Graphene is only one atom thick, optically transparent, chemically inert, and an excellent conductor. These properties seem to make this material an excellent candidate for applications in various photonic devices that require conducting but transparent thin films. In this letter, we demonstrate liquid crystal devices with electrodes made of graphene that show excellent performance with a high contrast ratio. We also discuss the advantages of graphene compared to conventionally used metal oxides in terms of low resistivity, high transparency and chemical stability.
