We report the fabrication of a highly flexible indium
tin oxide (ITO) electrode that is completely transparent to light
in the visible spectrum. The electrode was fabricated via the formation
of a novel ITO nanoarray structure, consisting of discrete globular
ITO nanoparticles superimposed on an agglomerated ITO layer, on a
heat-sensitive polymer substrate. The ITO nanoarray spontaneously
assembled on the surface of the polymer substrate by a simple sputter
coating at room temperature, without nanolithographic or solution-based
assembly processes being required. The ITO nanoarray exhibited a resistivity
of approximately 2.3 × 10<sup>–3</sup> Ω cm and
a specular transmission of about 99% at 550 nm, surpassing all previously
reported values of these parameters in the case of transparent porous
ITO electrodes synthesized via solution-based processes at elevated
temperatures. This novel nanoarray structure and its fabrication methodology
can be used for coating large-area transparent electrodes on heat-sensitive
polymer substrates, a goal unrealizable through currently available
solution-based fabrication methods.
