Copper-coated TiN nanofibers with high electrical conductivity: a new advance in conductive one-dimensional nanostructures

High electrical conductivity has been achieved in ceramics with a heterostructure design. We managed to incorporate an inexpensive metal into conductive nitride nanofibers. Low sheet resistance and high optical transparency were obtained on the nanofiber patterns, which indicate that it may serve as a new material for transparent electrodes.
