| Abstract: | Studies of the crystal structure, elemental composition, and dielectric properties of strontium titanate films in SrTiO3/CeO2/Al2O3 multilayered structures are reported. Data on the crystal lattice and impurity contents have been obtained, and temperature and electric field dependences of the dielectric properties of SrTiO3 films in the microwave range have been measured. An analysis of the results is made to establish the reason for the nonmonotonic dependence of the small-signal dielectric permittivity of SrTiO3 films on temperature. Fiz. Tverd.
