| Outline of Final Research Achievements |
In this research, we tried to create a microscale single crystal, develop new functions, and create a device by using our unique device manufacturing methods, the “nanoscale electrocrystallization” and the “photoinduced conductive crystal growth method”. In the nanoscale electrocrystallization, it was shown that it is possible to fabricate organic nanocrystals with various donor/acceptor materials, and to apply the nanocrystals as two-terminal devices. In the characteristic evaluation, the electric field dependence of the current-voltage characteristics was evaluated. In the characteristics, weak field effect which is depended on the external electric field were obtained. In optical functional devices, it has been shown that the photoelectric conversion characteristics can be measured. In addition, the possibility of controlling the electronic properties by material design was examined, and it was shown that the conductivity could be controlled by adjusting the counter component.
