| Outline of Final Research Achievements |
Recently, rapid progress has been made in organic semiconductor research. However, understanding of the basic properties such as carrier transport mechanism is not sufficient. We developed novel methods to investigate the electronic devices based on the spectroscopic measurement. We successfully visualize the carrier transport by using fluorescence decay imaging, and we could analyze the anisotropic carrier transport property. For the organic thin film transistors with ferroelectric gate insulator, we could observe the strong relationship between the polarization in the ferroelectric layer and the electric field in organic semiconductor.
