| Outline of Final Research Achievements |
Self-assembled single-crystalline metal oxide nanowires are attractive nanomaterials due to their various functionality, stability in air/water, spatially selective growth and designable structure. However, an unintentional doping in metal oxide nanowire has hindered the extraction of intrinsic nature of metal oxide nanowires and therefore it has been a long-standing issue in this research field. In this study, the generation mechanism of such unintentional doping, which is based on two competitive crystal growth interfaces, was successfully clarified and a rational design concept to synthesize the highly crystalline metal oxide nanowires with drastically suppressed unintentional doping was demonstrated for the first time. These findings will pave a way to extract the various fascinating functionalities of metal oxide nanowires towards novel nanodevice applications.
