Single-monolayer inkjetted oligothiophene organic TFTs exhibiting high performance and low leakage

Abstract

Through the use of a novel oligothiophene precursor, we have demonstrated organic TFTs exhibiting relatively high mobility while simultaneously retaining ultra-low leakage and excellent on-off ratios. The unique tendency of this material to self-assemble into a crystalline morphology allows non-uniform printed droplets to reorganize into high-quality monolayers. The resulting structure provides excellent electrostatic characteristics, ideal for low power analog applications.
