摘　　要：通过溶胶．凝胶法在Si（100）表面制备了钛酸铅薄膜，利用XRD、AFM技术考察了煅烧温度与薄膜表面形貌及结构的关系。结果表明，随着煅烧温度提高，薄膜表面变的粗糙，而且由于相转化使构成薄膜的颗粒粒径变大。Lead titanate thin films was synthesized on Si（100） substrate by sol-gel method. The relationship between the temperature and the characteristics of the films＇morphology, microstructure can be examined by XRD, AFM. The results demonstrated that higher annealing temperatures increase surface roughness and promote increased grain size due to the phase transformations, which were induced within the microstructure.
