The advantages of organic field-effect transistors (OFETs), such as low cost, flexibility and large-area fabrication, have recently attracted much attention due to their electronic applications. Practical transistors require high mobility, large on/off ratio, low threshold voltage and high stability. Development of new organic semiconductors is key to achieving these parameters. Recently, organic semiconductors have been synthesized showing comparable mobilities to amorphous-silicon-based FETs. These materials make OFETs more attractive and their applications have been attempted. New organic semiconductors resulting in high-performance FET devices are described here and the relationship between transistor characteristics and chemical structure is discussed.
有机场效应晶体管(OFET)具有低成本、柔韧性和大面积制造等优点,近年来因其电子应用而备受关注。实用的晶体管需要高迁移率、大的开/关比、低阈值电压和高稳定性。开发新型有机半导体是实现这些参数的关键。最近,已合成出与非晶硅基场效应晶体管具有相当迁移率的有机半导体。这些材料使OFET更具吸引力,并已尝试其应用。本文描述了能实现高性能场效应晶体管器件的新型有机半导体,并讨论了晶体管特性与化学结构之间的关系。
