We present hybrid transparent conducting films based on silver nanowires (Ag NWs) and doped graphene (GP) through dual co-doping method by applying p-/n- type dopants on top and bottom sides of GP. We systematically investigated the dual-doping effect on their surface and electrical-optical properties of GP and Ag NW/GP hybrid films through the combination study with various dopants (p/p, p/n, n/p, and n/n). We found that p/p-type dual-doped GP and its hybrid with Ag NWs appeared to be the most effective to enhance electrical-optical properties of doped monolayer GP (ΔR/R0=84 %, TT=97.4%) and Ag NW/doped GP hybrid (ΔR/R0=62%, TT=95.0%). Note that, dual-doping improved such electrical properties without any significant debilitation of optical transparency of conductors. In addition, the enhanced conductivity of p-type dual-doped GP allows a hybrid system to form co-percolating network in which Ag NWs can form a secondary conductive path at grain boundaries of polycrystalline GP. |
