Abstract

The transformation to perovskite phase of Pb_0.91La_0.09Zr_0.65Ti_0.35O₃ (9/65/35) films on r-sapphire and resulting annealed microstructures were examined by transmission electron microscopy. A random equiaxed polycrystalline grain morphology (approximately 600 nm) was observed after rapid-thermal annealing or furnace annealing when the as-deposited (radio-frequency-magnetron sputtering) films were predominantly pyrochlore. However, an interesting paired-plate structure was revealed after furnace annealing when the as-deposited films were fully perovskite. The average size of such a split precipitate was 35 nm in width and 150 nm in length.
