Abstract :
Ferroelectric epitaxial Pb(Zr0.9Ti0.1)O3 thin films have been successfully obtained on platinum-coated sapphire substrates by reactive sputtering of the multimetal target. The films with a perovskite structure have been epitaxially grown at substrate temperatures of 600-620°C. The crystallinity of the Pb(Zr0.9Ti0.1 )O3 film depended on the substrate temperature and the crystallinity of the platinum film used as a bottom electrode. The remanent polarization and the coercive field of a 0.75-μm-thick film were measured as 13.9 μC/cm2 and 60.0 kV/cm, respectively
