Transparent Aluminum Nanomesh Electrode Fabricated by Nanopatterning Using Self-Assembled Nanoparticles

A novel transparent aluminum nanomesh electrode with nanoapartures smaller than the wavelength of the light was proposed. Unlike conventional conducting oxides such as indium tin oxide, it has the potential to realize a rare-metal-free and low-resistivity transparent electrode. It was fabricated by nanopatterning with our embedded particle monolayer method, which enables the formation of a self-assembled particle monolayer over a large area, and its optical properties were investigated. As a result, the transmittance of the fabricated aluminum nanomesh electrode was found to be more than 55% at the peak wavelength when the opening ratio was 47%.
