Application of new electrode materials in N-type OFET

相比于无机场效应晶体管,有机场效应晶体管(OFET)具有制备工艺简单、成本低、柔性、透明等优点,在柔性电子产品、可穿戴器件等领域中有广泛用途。电极作为OFET器件的一个重要组成部分,其影响OFET器件的整体性能。为了提升电极性能,一方面可以对金属电极进行修饰,另一方面可以使用聚合物等新材料来制作OFET电极。围绕新型电极材料在N型OFET中的应用展开综述。首先,介绍OFET的一般器件结构。接着依次介绍了修饰金属电极、聚合物电极、碳基电极、无机化合物电极和纳米线电极的N型OFET进展。最后,总结全文,并对OFET新型电极材料的未来发展做出了展望。

Compared with traditional field effect transistor, OFET has the advantages of simple preparation process, low cost, flexibility, transparency and so on. It is widely used in flexible electronic products, wearable devices and other fields. As an important part of OFET devices, electrodes affect the overall performance of OFET devices. In order to improve the performance of the elec-trode, on the one hand, the metal electrode can be modified, on the other hand, new materials such as polymer can be used to make OFET electrode. This paper reviews the application of new electrode materials in N-type OFET. Firstly, the general device structure is introduced. Then the development of N-type OFET using modified metal electrode, polymer electrode, carbon based electrode, inorganic compound electrode and nanowire electrode is introduced. Finally, the full text is summarized, and the future development of OFET new electrode materials is prospected.
