Organic Thin Film Transistors Using Liquid Crystalline Organic Semiconductor for High Speed and Low Energy Fabrication Process

Abstract

Organic semiconductors are good materials for green technology with low energy consumption for the fabrication of electronic devices. In this paper, liquid crystals are focused as suitable materials for organic semiconductors. Liquid crystals have self-organization manner, which helps the fabrication of uniform and flat crystalline thin film by common solution process. In fast speed solution process such as dip coating and blade coating techniques, the usage of liquid crystallinity is key factor to fabricate the uniform and flat crystalline thin films, which show high mobility over 4cm²/Vs and small variation of transistor performance. Therefore, the liquid crystals are a good candidate for organic semiconductor materials having high productively and high transistor performance.
