Outline of Final Research Achievements

In this research, we tried to find novel functions and to fabricate devices using our original method, the nanoscale electrocrystallization, and materials. In a case of electronic devices, we succeeded to fabricate organic nanocrystal based novel field-effect transistors using various materials. We also observed unusual characteristics whose mechanism have to be clarified continuously. In another case of magnetic devices, we first observed negative giant magnetoresistance in a nanocrystal. In the other case of photonics devices, we found a phenomenon of a crystal growth of a charge transfer complex by photoirradiation only. Our results will lead to a eco-friendly nanodevice fabrication in the future.
