Motivated by the rising cost of tin-doped indium oxide (ITO), the search for new transparent electrode materials to replace ITO is ongoing. TiN exhibits high electric conductivity, however, it is generally non-transparent. Here, nanostructured TiN fiber patterns are synthesized on quartz glass and the resulting materials have a combination of high electric conductivity and optical transparency. A low sheet resistance of 15.8 Ohm sq−1 at 84% transparency is achieved on TiN nanofiber arrayed quartz glass. The achievements show a successful integration of electric and optical properties in ceramic nanofibers and provide a method for finding new materials to replace traditional ITO-based transparent electrodes.
