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

Abstract

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