| Outline of Final Research Achievements |
We attempted to decrease the drain current under the off-state (i.e., the off-current) by insertion of a blocking layer between an organic active layer and carrier generation layer in carrier-generation type organic field-effect transistors (CG-OFETs).
It is found in our study that the conduction current that flows through the interface between an organic active layer and carrier generation layer can be decreased by insertion of a blocking layer. Moreover, it is experimentally clarified that the off-current can be controlled by fine patterning the carrier-generation layer in CG-OFETs. It is supposed that these results are useful techniques for development of OFETs having a high ON/OFF ratio characteristic.
