摘要: 典型的压电材料Pb(Zr0.52,Ti0.48)O3因其优异的性能,可用来制备各种类型的压电器件,一直受到许多研究者的关注。采用 PLD 法在 SrTiO3(100) 单晶衬底上制备出了不同组分的 PZT 薄膜,讨论了不同激光能量和Zr/Ti比对Pb(Zr0.52,Ti0.48)O3薄膜结晶质量的影响,得出最佳生长 PZT 薄膜的条件,并分析其 (002) 摇摆曲线结果显示: (Zr0.52,Ti0.48)O3; 薄膜表面比较均匀,均方根粗度较小,体现出较好的结晶质量。最后根据谢乐公式可得出其所制备的薄膜晶粒尺寸在2~6 nm 范围内,可以用于器件制作。

Abstract: Pb(Zr0.52,Ti0.48)O3, is a typical piezoelectric material. It can be used to prepare all kinds of piezoelectric devices because of its excellent properties, and it has been widely concerned by many researchers. PZT thin films with different compositions were prepared on SrTiO3(100)single crystal sub-strate by PLD method. The effects of laser energies and Zr/Ti ratio on the crystallization quality of Pb(Zr0.52,Ti0.48)O3, thin films were discussed. The optimum conditions for the growth of PZT films were obtained. The rocking curves of (002) were analyzed. The results show that the Pb(Zr0.52,Ti0.48)O3, filmswith uniform surface and small root mean square roughness are obtained, reflecting better crystallization quality. The grain size of the film prepared in the 2 to 6 nm range according to the formula can be used indevice fabrication.

Key words:  PZT thin film, laser energy, Zr/Ti ratio, crystalization quality
