(a) X-ray diffraction (XRD) patterns of the ITO/metal NW-GFRHybrimer films. (b) A plot of sheet resistance (Rsh) vs annealing time for the ITO-only (half-filled), ITO/AgNW-GFRHybrimer (filled) and ITO/CuNW-GFRHybrimer (voided) films with various ITO thicknesses. Triangles, reverse triangles and circles indicate an ITO thickness of 10, 20 and 30 nm, respectively; filled and voided squares indicate the bare AgNW- and CuNW-GFRHybrimer films, respectively. Refer to Supplementary Information for more detail. (c) The total transmittance (Ttot) vs Rsh for various transparent electrodes. (d, e) Conductive atomic force microscopy (c-AFM) scan images, with current mappings for the (d) AgNW-GFRHybrimer and the (e) c-ITO/AgNW-GFRHybrimer. The scale bar, 400 nm (bottom images are schematic illustrations of the transparent conducting electrodes (TCEs)). AgNW, silver nanowire; c-ITO, crystalline indium tin oxide; CuNW, copper nanowire; NW, nanowire.
