Abstract
Disclosed are a noble metal nanowire oriented to a surface of a single crystalline substrate, which is prepared using a noble metal oxide, noble metal or noble metal halide as a precursor and, in addition, a method for preparation of the same. The present invention adopting a vapor phase transport method to prepare the noble metal nanowire without any catalyst has advantages of simplifying and reproducing processes of the method and enabling mass production thereof. The prepared nanowire exhibits high purity and quality and a complete crystalline state without defects and/or impurities. The prepared noble metal nanowire also has orientation to a surface of a single crystalline substrate and alignment of the nanowire as well as the orientation can be controlled.
