The ability to explore organic materials for device fabrication requires patterning the films in a controlled way. Unfortunately, photolithography with high resolution and high uniformity over large areas cannot simply be implemented for organic semiconductors (OSCs) owing to their fragility. Current patterning techniques for organic materials, e. g. shadow mask and printing still suffer to some extent from low resolution and poor scalability. A number of researchers have sought to pattern the OSCs with photolithography by sealing organic layers between metal layers or using fluorinated chemicals. However, the processes are still facing complicated multi-step procedures or high costs.The purpose of this project is to obtain patterned functional organic structures with mesoscopic resolution based on top-down directed bottom-up strategy. In particular, we aim at developing cross-talk free, high cut-off frequency organic field-effect transistors (OFETs) and their basic digital circuit blocks. We will focus on the following aspects: 1) Improving the carrier mobility of short channel OFETs by designing molecules and optimizing the crystallization process; 2) reducing organic/electrode contact resistance by surface/interface modifications; 3) AC and DC characterization of short channel OFETs and their basic digital circuit blocks.

探索用于器件制造的有机材料的能力需要以受控的方式对薄膜进行图案化。不幸的是，由于有机半导体(OSC)的脆弱性，高分辨率和高均匀性的大面积光刻不能简单地应用于有机半导体。目前用于有机材料的图案化技术，例如荫罩和印刷，仍然在一定程度上受到分辨率低和可扩展性差的影响。许多研究人员试图通过在金属层之间密封有机层或使用氟化化学物质，用光刻技术对OSCs进行图案制作。本项目的目的是基于自上而下定向自下而上的策略，获得具有介观分辨率的图案化功能有机结构。特别是，我们的目标是开发无串扰、高截止频率的有机场效应晶体管(OFET)及其基本数字电路模块。我们将集中在以下几个方面：1)通过分子设计和优化结晶工艺来提高短沟道OFET的载流子迁移率；2)通过表面/界面修饰来降低有机/电极接触电阻；3)短沟道OFET及其基本数字电路模块的交流和直流特性。
