Abstract

Dense polycrystalline thin films of ZrO2 (3 and 8 mol% Y2O3) were produced by the pyrolysis of zirconium acetate precursor films, which were deposited on single crystal Al2O3 substrates by spin-coating solutions of zirconium acetate. With grain growth, these films broke into islands of ZrO2 grains. Thermodynamic calculations show that this break up lowers the free energy of the system. These calculations also predict the conditions needed for polycrystalline thin film stability.
