Mg-doped LaFeO3 thin film and Mg, Cr-doped La0.5Sr0.5FeO3 thin films were prepared by the sol-gel method. The change rules of structure and dielectric properties of the films were studied by XRD, SEM, and Agilent. The dielectric properties of La0.5Sr0.5FeO3 and LaFeO3 films were improved by the substitute with Mg and Cr. The doping amount of Mg and Cr for the optimal dielectric properties of La0.5Sr0.5FeO3 films is 45mol%, 25mol%, respectively, and for LaFeO3, the doping amount of Mg is 8mol%. The observed pure perovskite phase of the doped films suggested the dissolution of Mn, Co, and Ni in La0.5Sr0.5FeO3 crystal lattice. Mg and Cr were integrate in the lattice of LaFeO3 and La0.5Sr0.5FeO3, and mineral is single perovskite phase. The surface of the film is smooth, without cracks, surface grain size distribution and had uniform grain size.

( Bi 1-x Ce x)2 Ti 2 O 7 thin films were grown on p- Si 〈100〉 substrates by chemical solution decomposition method. The relationship between the doping levels of cerium ions and the phase transition temperatures was studied. The doping of cerium ions could improve the phase stability of Bi 2 Ti 2 O 7, and the reason was comprehensively explained by the charge compensating theory. The doping of Ce ions enhances the crystallization temperature, which make the crystallization difficult, so the amount of cerium ions should be kept appropriate. The dielectric properties of ( Bi 1-x Ce x)2 Ti 2 O 7 thin films with different X values at different temperatures and different doping levels were listed, and the latent variation tendency was found. When the annealing temperature was 650–700°C and X = 0.12 or 0.16, the thin films showed better dielectric properties than the others.
