High-mobility flexible pentacene-based organic field-effect transistors with PMMA/PVP double gate insulator layers and the investigation on their mechanical flexibility and thermal stability

Abstract

High performance pentacene-based OFETs with excellent mechanical flexibility and high thermal stability were fabricated with PMMA/PVP double dielectric films as double gate insulator layers on a PET plastic substrate. The μ increased from 0.66 to 1.51 cm² V⁻¹ s⁻¹.
