有机电介质对场效应晶体管性能的影响

The Effect of Organic Gate-dielectric on Field-effect Transistor Characteristics

电介质层是有机场效应晶体管(OFETs)的重要组成部分,其材料选择影响着器件的性能。简要介绍了有机场效应晶体管,总结了电介质层对器件性能的影响(包括介电常数、电介质表面粗糙度、电介质表面能及处理工艺),并探讨了近年来常用作电介质的材料。

The dielectric layer is an important part ot of dielectric material impacts on the performance of OFETs. A brief introduction to organic field-effect transistors is presented. The influence of dielectric layer（including dielectric constant, surface roughness of dielectric, surface energy of dielectric,and process） on device performance is summarized. The commonly used dielectric materials are discussed.
