| Outline of Final Research Achievements |
We have realized the manufacturing process of high-performance, high-yield organic field-effect transistors using nano-hetero structure based self-assembled monolayer gate dielectrics (SAM). The organic transistors manufactured on 5-micrometer flexible substrates exhibited mobility greater than 1 cm2/Vs with low-operation voltages (<2 V). Furthermore, taking full advantages of the transistors with very small device-to-device non-uniformity, we have developed signal amplifier and ring-oscillators. The proposed organic transistors with using nano-hetero structure based SAM were used for constructing an array of active matrix amplifier, whose amplifier gain is more than 55 dB, and amplified bio-signals, indicating excellent feasibility of the transistors developed in this work. This work has been published in Nature Communications.
