Title Growth of Lead Zirconete Titanate Thin Films by Pulsed-Laser Deposition
Abstract
In this thesis, we deposited PZT thin films with Pb(Zr0.52Ti0.48)O3 ceramic target by PLD method, and studies the influences of substrate temperature and annealing temperatures on the films.
PZT films were deposited at various substrate temperatures and various annealing temperatures. The structure and morphology were characterized with both X-ray diffraction (XRD) and scanning electronic microscopy (SEM). The analysis of the measurement results shows that a lower substrate temperature is not suitable for the crystallization of PZT thin film. When the substrate temperature is lower than 450℃, the film becomes amorphous. Annealing temperature affects the preferred orientation of the PZT film, and it changes from (102) after low-temperature annealing to (200) after high-temperature annealing.
