| Outline of Final Research Achievements |
Identifying and controlling properties of grain boundaries in organic thin films is essential to reducing the energy loss of the device. In this study, we clarified the correlation between the aggregation structure (defect structure) of the molecules near the grain boundaries and their electronic properties. We demonstrated in detail what kind of grain boundary structure causes the energy loss of the devices.
