Fabrication of Functional Ceramic Composites - Zinc Oxide of Organic Self-Assembled Monolayers
Abstract
This films and multilayers of functional ceramics have a number of important applications including dielectrics, magnetic recording media, piezoelectric transducers, and integrated optical devices. Variously functionalized self-assembled monolayers, attached to single-crystal silicon substrates, were used to direct the deposition of thin films of the oxides of titanium, zine, iron, and zirconium, at low temperatures and ambient pressures. The films were uniform, adherent, and pore-free and were, in many cases, comprised of micro-crystalline oxide particles. The monolayer functionality found to be most generally useful for these purposes included hydroxyl, carboxylate, and sulfonate functionality. In some cases the films contained desirable forms of the oxides that were different than those normally obtained i.e., the anatase form of titania as opposed to tutile; and the tetragonal form of zirconia as opposed to the monoclinic version. The patterning of the oxide films by patterning the underlying monolayer was also demonstrated. The project developed new technologies for the production of functional ceramics hy creating template for their deposition from solution and as such is a first step towards the generalized control of microstructural and crystallographic order by interface design in composite organic/inorganic materials.
