Engineering of the dielectric-semiconductor interface in organic field-effect transistors

With the advances of organic field-effect transistors (OFETs), the interface between semiconductors and dielectrics has received much attention due to its dramatic effects on the morphology and charge-transport of organic semiconductors in OFETs. The purpose of this review is to give an overview of the recent progress in the engineering of the dielectric-semiconductor interface in OFETs. The interface-dependent performances of OFETs are reviewed, and interfacial control methods are especially dealt with an aim to solve interfacial effects. Finally, novel applications of the dielectric-semiconductor interface for achieving multifunctions are summarized to offer a clear map of interface engineering in OFETs.
