Abstract

A transparent conducting metal (TCM) composed of a stack of a gold film and silver/polymer nanocomposite fabricated by sputtering onto a glass substrate is presented. The plasmonic metamaterial shows an omnidirectional optical transmission up to 80% in the visible spectrum, which is comparable to that of ITO, and the electrical conductivity is one order of magnitude higher than that of ITO.
