Abstract

We demonstrate the easy fabrication of textured gold films with a microstructure resembling a bunch of Romanesco broccoli, using an easily scalable process based on electrodeposition. These gold films display highly suppressed reflection of light over a large range of wavelengths and angles of incidence. Less than 1% of light is reflected at angles of incidence up to 65u, for both s- and p-polarized light. The gold films are good candidates for low cost, high efficiency absorber materials.
