ALL-INKJET PRINTED THIN FILM TRANSISTOR

摘要

A method is provided for making a thin film transistor comprising the steps of: providing a substrate; applying a gate electrode ink by inkjet printing; applying a dielectric ink over by inkjet printing; applying a semiconductor ink by inkjet printing; and applying a source and drain electrode ink by inkjet printing. In some embodiments the semiconductor ink comprises a solvent and a semiconducting material comprising: 1-99.9% by weight of a polymer; and 0.1-99% by weight of a functionalized pentacene compound as described herein.
