Interface engineering for high-performance organic field-effect transistors.

The performance of organic field-effect transistors (OFETs) depends not only on the properties of organic semiconductors, gate dielectrics and electrodes, but it is also determined by the nature of the contact interfaces between the different functional components. Therefore, interface engineering to optimize the contacts becomes critically important for the fabrication of high performance OFETs. In this Perspective, representative strategies of interface engineering and the basic requirements for different functional components to enable high performance OFETs are highlighted.
