TCO Nanostructures as building blocks for nanophotonic devices in the infrared

Transparent conducting oxides (TCOs), in general, are degenerated semiconductors with large electronic band-gap. They have been widely used for display screens, optoelectronic, photonic, and photovoltaic devices due to their unique dual transparent and conductive properties. In this study, we report in detail a technique that we developed to fabricate single crystal TCO nanorod arrays with controlled conductivity, height, and lattice spacing in a simple one-zone tube furnace system. We demonstrate how novel photonic/plasmonic properties can be obtained by selecting unique combinations of these basic parameters of the nano-rod arrays.
