Organic field-effect transistors (OFETs) have gathered great interest in the last decade because of the potential application to low-cost printed electronics and large-area flexible electronic devices [1, 2]. In particular, fabrication techniques such as ink-jet printing, micro-contact printing, and roll-to-roll processing of polymeric functional materials enable the realization of high performance solution-processed OFETs [3, 4, 5, 6, 7]. Recently, many groups have observed that the performance of OFETs can be significantly improved by treating the insulator surface with self-assembled monolayer (SAMs) such as octadecyltrichlorosilane (OTS) [8, 9, 10], fluoroalkyltrichlorosilane (FTS) , and phenyltrichlorosiane (PTCS) [12, 13, 14]. SAMs modification of dielectric surface provides emerging applications for semiconductor molecules to achieve optimum molecular ordering and crystallinity for charge carrier transport. For example, SAMs can enhance a wettability of the gate dielectric...
