  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.
