Abstract
We have demonstrated fast operation of printed organic inverter circuits. We employ a soluble organic semiconducting material which has high field-effect mobility and ink-jet printed source/drain electrodes with short channel length. Appropriate concentration of the semiconducting solution and modification layer of source/drain electrodes improve both mobility and on/off ratio. The fabricated transistors with a short channel length (4μm) exhibit excellent mobility (1.2cm2/Vs), high on/off ratio (>105) and operational stability. The diode-load inverter with a narrow channel and low parasitic capacitance operate at 8kHz at 20V. These results will lead to significant progress in applications of printed organic circuits.
