“…Substrate-induced lattice strain, substrate surface morphology and growthinduced defects are some examples for extrinsic effects playing an important role in determining thin-film properties and consequently the application potential of functional ceramics [1][2][3][4][5]. The sensitivity of the physical properties on the structure arises from the origin of the functionality at the level of sub-unit cells.…”

A concept is introduced, using oxide substrates for functional ceramic thin film deposition beyond their usual application as chemical inert, lattice-matched support for the films. The substrates are applied as a functional element in order to controllably modify the atom arrangement and the growth mode of cuprate superconductors and colossal magnetoresistance materials. These materials have been chosen as prototypes of the general class of perovskite functional ceramics. One example studied is the use of epitaxial strain to adjust the relative positions of cations and anions in the film and thus modify their physical properties. The other makes use of vicinal cut SrTiO 3 which enables the fabrication of regular nanoscale step and terrace structures. In YBa 2 Cu 3 O 7−x thin films grown on vicinal cut SrTiO 3 single crystals a regular array of antiphase boundaries is generated causing an anisotropic enhancement of flux-line pinning. In the case of La-Ca-Mn-O thin films grown on vicinal cut substrates it could be demonstrated that magnetic in-plane anisotropy is achieved.

“…The physical properties of perovskite-type functional ceramic thin films are known to sensitively depend on details of deviations from their ideal composition and/or crystal structure. Therefore, substrateinduced lattice strain, substrate surface morphology and growth-induced defects are some examples for extrinsic effects playing an important role in determining thin-film properties and consequently the application potential of functional ceramics [1][2][3][4][5]. The sensitivity of the physical properties on the structure arises from the origin of the functionality at the level of sub-unit cells.…”

Published online zzz PACS 68.55Jk, 74.76Bz, Using oxide substrates for functional ceramic thin film deposition beyond their usual application as chemical inert, lattice-matched support for the films represents a novel concept in ceramic thin film research. The substrates are applied as a functional element in order to controllably modify the atom arrangement and the growth mode of ceramic prototype materials such as cuprate superconductors and colossal magnetoresistance manganites. One example is the use of epitaxial strain to adjust the relative positions of cations and anions in the film and thus modify their physical properties. The other makes use of vicinal cut SrTiO 3 which enables the fabrication of regular nanoscale step and terrace structures.
