    • PROBLEM TO BE SOLVED: To provide a semiconducting composition that exhibits high field effect mobility, good film-forming properties, and proper morphology for high performance in a composite system.SOLUTION: A bottom-gate bottom-contact TFT 10 comprises a substrate 16 in contact with a gate electrode 18 and a gate dielectric layer 14. The gate electrode 18 is depicted here atop the substrate 16, but the gate electrode may also be located as a depression within the substrate. It is important that the gate dielectric layer 14 separates the gate electrode 18 from the source electrode 20, drain electrode 22, and the semiconducting layer 12. The semiconducting layer 12 formed of a semiconductor composition extends between the source electrode 20 and drain electrode 22. The semiconductor composition comprises a polymer binder and a small molecule semiconductor. The small molecule semiconductor in the semiconducting layer has a crystallite size of less than 100 nanometers. Devices formed of the composition exhibit high mobility and excellent stability.
    • 要解决的问题:提供一种在复合体系中表现出高的场效应迁移率,良好的成膜性能和适当的形态以获得高性能的半导体组合物。 解决方案:底栅底接触TFT 10包括与栅极电极18和栅极电介质层14接触的衬底16.栅电极18在这里被描绘在衬底16的顶部,但是栅电极也可以 位于底物内的凹陷处。 栅电介质层14将栅电极18与源电极20,漏电极22和半导电层12分开是重要的。半导体组合物形成的半导体层12在源电极20和漏电极22之间延伸。 半导体组合物包含聚合物粘合剂和小分子半导体。 半导体层中的小分子半导体的微晶尺寸小于100纳米。 由该组合物形成的装置显示高迁移率和优异的稳定性。 版权所有(C)2013,JPO&INPIT
