Popis: 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.
