TiN Nanofibers: A New Material with High Conductivity and Transmittance for Transparent Conductive Electrodes

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.
