Organic field-effect transistors (OFETs) are fundamental building blocks for flexible and large-area electronics due to their superior solution-processability, flexibility and stretchability. OFETs with high ideality are essential to their practical applications. In reality, however, many OFETs still suffer from non-ideal behaviors, such as gate-dependent mobility, which thus hinders the extraction of their intrinsic performance. It is much desired to gain a comprehensive understanding of the origins of these non-idealities. OFETs are primarily interface-related devices, and hence their performance and ideality are highly dependent on the interface properties between each device component. This review will focus on the recent progress in investigating the non-ideal behaviors of OFETs. In particular, the roles of interfaces, including the organic semiconductor (OSC)/dielectric interface, OSC/electrode interface and OSC/atmosphere interface, in determining the ideality of OFETs are summarized. Viable approaches through interface optimization to improve the device ideality are also reviewed. Finally, an overview of the outstanding challenges as well as the future development directions for the construction of ideal OFETs is given.

接口在有机场效应晶体管理想化中的作用。

有机场效应晶体管(OFET)由于具有出色的溶液加工性,灵活性和可拉伸性,因此是柔性和大面积电子产品的基本构建模块。高理想的OFET对他们的实际应用是必不可少的。但是,实际上,许多OFET仍然遭受非理想行为的影响,例如依赖门的迁移率,因此阻碍了其内在性能的提取。迫切需要对这些非理想的起源有一个全面的了解。OFET主要是​​与接口相关的设备,因此它们的性能和理想性高度取决于每个设备组件之间的接口属性。这篇综述将集中在研究OFET的非理想行为方面的最新进展。特别是界面的作用 在确定OFETs的理想性时,总结了包括有机半导体(OSC)/介电界面,OSC /电极界面和OSC /大气界面在内的所有信息。还回顾了通过接口优化来提高设备理想性的可行方法。最后,概述了理想的OFET的建设面临的挑战和未来的发展方向。
