Transparent conductive electrodes (TCEs) are produced using a bottom-up approach. Hydrophobically coated gold nanoparticles (Au NPs) assembled within surfactant monolayer templates formed at the air/water interface. The Au NP network is then transferred onto solid substrates and becomes scaffolding for further enhancement. resultant thin films exhibit excellent transparency electrical conductivity from nanometer to centimeter scales.
