title: Grain growth in nanocrystalline yttrium-stabilized zirconia thin films synthesized by spin coating of polymeric precursors.
abstract: This article reports results of experimental studies on the microstructural evolution of nanocrystalline yttrium-stabilized zirconia thin films synthesized on a Si substrate via a polymeric precursor spin-coating approach. Grain growth behavior has been investigated at different annealing temperatures (700-1200 degrees C) for periods of up to 240 h. A similar film thickness (approximately 120 nm) was maintained for all of the samples used in this study, to avoid variation in film thickness-dependent grain growth. The effects of the thermal history of the film and the annealing atmosphere on the grain growth were also studied. A simple semiempirical grain growth model has been developed to describe isothermal annealing data and to predict dynamic grain growth behavior during the sintering of polymeric precursor layers to form cubic-phase nanocrystalline yttrium-stabilized zirconia films.
