In this work, we manipulated the crystallinity and geometry of P3HT nanodomains and investigated their effects on carrier mobility of organic thin film transistor (OTFT). Furthermore, it was confirmed that the reproducibility of OTFT devices could be improved with nanostructure-based active layer. P3HT nanostructures, nanodot and nanowire, were prepared through the control of polymer solution concentration and ultrasonic treatment. Those nanostructures produced well-organized crystalline morphology, which resulted in outperforming field-effect mobility, compared to bulk P3HT film, thermally annealed after spin-casting. OTFT devices fabricated with P3HT nanowires showed slightly higher electrical mobility than those with nanodots, due to their geometric advantage for inter-connection between electrodes. In terms of device-to-device uniformity, nanodot-based devices have lower performance variation among OTFT arrays due to their symmetric geometry.
