| Outline of Final Research Achievements |
Nanosecond time-resolved microscopic gate-modulation imaging method is developed to examine carrier conduction dynamics of polycrystalline thin-film transistors under operation. The developed method allows clarifying microscopic local carrier conduction mechanism on grain boundaries and electrode-semiconductor interfaces which have strong affects on device performance. Furthermore, it is found that the developed method can be used to visualize spatial distribution of domain boundaries for ferroelectric materials.
