Green Processing of Metal Oxide Core-Shell Nanoparticles as Low-Temperature Dielectrics in Organic Thin-Film Transistors

TiO2, Fe3O4, AlOx, ITO (indium tin oxide), and CeO2 nanoparticles are tailored to exhibit excellent dispersability in deionized water and alcohols. The latter provides an ecofriendly solution for processing metal oxide nanoparticles at a neutral pH. Water‐processed dielectrics from the metal oxide n...

Zusammenfassung:	TiO2, Fe3O4, AlOx, ITO (indium tin oxide), and CeO2 nanoparticles are tailored to exhibit excellent dispersability in deionized water and alcohols. The latter provides an ecofriendly solution for processing metal oxide nanoparticles at a neutral pH. Water‐processed dielectrics from the metal oxide nanoparticles are incorporated into organic thin‐film transistors fabricated on rigid and flexible substrates.
