Figure 1.

Transmittance (550 nm) plotted as a function of sheet resistance for thin films prepared from four nanostructured materials: graphene, single-walled carbon nanotubes, silver nanowires, and silver flakes. The dashed lines represent fits to the bulk regime using Equation (5), while the solid lines represent fits to the percolative regime using Equation (9).
