Green Processing of Metal Oxide Core-Shell Nanoparticles as Low-Temperature Dielectrics in Organic Thin-Film Transistors
Luis Portilla, Sebastian H. Etschel, Rick R. Tykwinski, and Marcus Halik Abstract 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 […]
Region-Selective Deposition of Core-Shell Nanoparticles for 3D Hierarchical Assemblies by the Huisgen 1,3-Dipolar Cycloaddition
Sebastian H. Etschel, Luis Portilla, Johannes Kirschner, Martin Drost, Fan Tu, Priv.-Doz. Dr Hbertus Marbach, Prof. Dr. Rik R. Tykwinski, Prof. Dr. Marcus Halik Abstract Like a NP-needle in an azide-stack: Metal oxide nanoparticles functionalized with alkyne- and azide-bearing phosphonic acids were assembled in defined stacks with precise control over region-selectivity and layer composition by […]
