| Outline of Final Research Achievements |
Three-dimensional organic transistors comprising vertical short channels are developed to raise the operational speed of organic transistors. The devices with a short-channel length of 0.8 micrometer and reduced parasitic capacitance operate at up to 20 MHz with an applied drain voltage of -15 V. Organic rectifiers based on the diode-connected 3D-OFETs are also demonstrated to operate at above 80 MHz, even with an applied effective voltage of about 4 V. Furthermore, solution-processed p-type and n-type organic transistors with short channels were developed utilizing single-crystalline organic semiconductor films, minimizing the process damage to organic semiconductors. Transient dynamic responses were measured for the both devices in respect to the dependence on the carrier density and temperature. These findings will accelerate the development of organic logic circuits and contribute to the future realization of practical applications in organic electronics.
