A method for forming well-aligned metallic nanowires includes: (a) providing a substrate formed with a crystal layer thereon; (b) disposing the substrate in such a manner that the crystal layer faces downwardly; (c) applying a metal salt solution, which contains metal ions therein, to the crystal layer on the substrate; and (d) subjecting the metal ions in the metal salt solution on the crystal of TiO2 layer to a reduction treatment, thereby resulting in reduced metal that grows downward toward earth's gravity.
