In this paper, we report about the preparation of novel nanocomposite films based on graphene and Poly (3,4 ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS). It has been observed that the prepared nanocomposite material shows excellent electrical conductivity of 60 S/cm and highly transparent (>90%) in the visible region. The resistivity of graphene and PEDOT:PSS nanocomposite films decreases as temperature increases, which is a characteristic behavior of semiconductors. The conductivity of nanocomposite film is enhanced by two orders of magnitude as compared to pristine PEDOT:PSS film. Au/graphene-PEDOT:PSS nanocomposite/n-Si/In-Ga diodes are fabricated and it exhibited rectifying behavior.

在本文中，我们报道了有关基于石墨烯和聚（3,4-乙撑二氧噻吩）-聚（苯乙烯磺酸盐）（PEDOT：PSS）的新型纳米复合薄膜的制备方法。已经观察到，所制备的纳米复合材料显示出60 S / cm的优异电导率并且在可见光区域中具有高度透明（> 90％）。石墨烯和PEDOT：PSS纳米复合膜的电阻率随温度的升高而降低，这是半导体的特征行为。与原始的PEDOT：PSS膜相比，纳米复合膜的电导率提高了两个数量级。制备了Au /石墨烯-PEDOT：PSS纳米复合材料/ n -Si / In-Ga二极管，并表现出整流性能。
