Abstract

We investigated the impact of interface modification by an octadecyltrichlorosilane self-assembled monolayer (OTS-SAM) on growth mode and transistor performance of quaterrylene thin films. Interface modification by OTS-SAM contributed effectively to stress-free film growth and highly molecular ordering, particularly in the initial layers, dramatically improving transistor performance. We found that the structural features in a few layers were key factors for determining the overall thin film growth mode and ameliorating carrier transport in organic field-effect transistors (OFETs). These results clearly demonstrated the effectiveness of interface engineering in the OFETs.
