Highly Dielectric and Photo-patternable Gate Insulators for Organic Field-effect Transistors

Abstract

A highly dielectric and photo-patternable polymer material has been developed as a gate insulating layer in organic field-effect transistors (OFETs). The partially cyanomethylated poly(vinyl phenol) (PVPCM) was synthesized as a highly dielectric polymer matrix. The photosensitive PVPCM (PS-PVPCM) consisting of PVPCM (72 wt%
