The effect of phenylboronic acid-based self-assembled monolayers on the performance of organic field-effect transistors (OFETs)

Authors: TUĞBAHAN YILMAZ ALIÇ

Abstract: The dielectric/semiconductor interface is one of the most important components strongly affecting the performance of organic field-effect transistors (OFETs). To improve OFET parameters, we applied a series of phenylboronic acid derivatives as self-assembly molecules between dielectric and organic semiconductor layers. Device performance parameters, especially threshold voltage, current on/off ratio, and subthreshold slope, were improved. To elucidate the mechanism, dielectric/semiconductor interfaces were analyzed using atomic force microscope and contact angle techniques.

Keywords: Interface modification, self-assembled monolayer, organic field-effect transistor
