- Abstract:
- Lanthanum calcium-doped lead titanate (Pb0.8La0.1Ca0.1) Ti0.975O3 (PLCT) pyroelectric films were prepared by pulsed laser (PLD), the phase composition of the films was studied by wide-angle X-ray diffraction (XRD), the thickness of TiO2 seed layer was characterized by X-ray specular reflection, and the effect of TiO2 seed layer on the crystallographic texture of thin film crystallography and its diffusion degree was studied by X-ray diffraction and ω scanning. The results show that PLCT pyroelectric films of pure perovskite phase can be obtained at a suitable crystallization temperature. The introduction of the seed layer changes the texture type of the film, and when there is no seed layer, the film tends to form a (100) texture; The introduction of TiO2 seed layer was conducive to the formation of thin film (301) texture.
