Outline of Final Research Achievements |
In this research, we developed a high-speed operation device with organic field-effect transistors (FETs). As a result, in the Au top contact organic FETs, we clarified that an annealing process dramatically reduces the contact resistance. Also, we clarified that the cause of the mobility overestimation of the organic FET is due to the large contact resistance. Moreover, by optimizing process conditions, we realized the world's smallest contact resistance (50 ohm・cm). Finally, we succeeded in fabricating a low voltage operating flexible organic FET circuit.
