Abstract
We investigated the electrical properties of triisopropylsilyl (TIPS)-pentacene organic thin film transistors (OTFTs) fabricated with a photoreactive polymer. The OTFTs fabricated with annealing of the gate dielectric layer had a field-effect mobility of up to 0.06cm2 V -1 s-1, while those treated with ultraviolet (UV) irradiation showed a field effect mobility of 0.12cm2 V-1 s-1. The large improvement in TIPS-pentacene OTFT performance using a photoreactive dielectric layer is probably due to the enhanced alignment of TIPS-pentacene molecules and improved dielectric properties.
