    • The present invention provides an organic field-effect transistor (OFET) and a method of fabricating the OFET. The OFET, configured to function as a p-type semiconductor, includes a substrate having a top surface and a semiconductor layer located over the top surface. The semiconductor layer comprises organic semiconductor molecules. Each of the organic semiconductor molecules includes a core having conjugated pi bonds, a fluorinated alkyl group, and an alkyl spacer group having a chain of two or more carbon atoms. One end of the chain is bonded to the fluorinated alkyl group and another end of the chain is bonded to the core. Substituents coupled to the carbon atoms have an electronegativity of less than about 4.
    • 本发明提供有机场效应晶体管(OFET)和制造OFET的方法。 被配置为用作p型半导体的OFET包括具有顶表面和位于顶表面上方的半导体层的衬底。 半导体层包括有机半导体分子。 每个有机半导体分子包括具有共轭π键的核,氟化烷基和具有两个或更多个碳原子的链的烷基间隔基。 链的一端与氟化烷基结合,链的另一端与核结合。 与碳原子偶联的取代基具有小于约4的电负性。
