The across-plane conductivity and microstructure of SrZr0.95Y0.05O3 − δ thin films

Deposition and Characterization of Y-doped CaZrO 3 Electrolyte Film on a Porous SrTi 0.8 Fe 0.2 O 3-δ Substrate

“…The observed grained morphology indicates the 3d-island mode of the film growth. As shown for SrZr0.95Y0.05O3-δ film obtained by CSD, prolonged thermal treatment of the film (20 hours at 1000°C) promotes growth of grains up to micrometer scale[27]. However, from the other hand thermal treatment induces undesirable diffusion between the film and the substrate.…”

“…This technique was shown to be effective for deposition of calcium and strontium zirconates' films on dense substrates [26][27][28]. Because of the low viscosity of solution compared to that of sol, the solution (i) forms a thinner layer on the substrate surface that allows reducing cracking in the film during drying and sintering and (ii) easier fills the pores of the substrate.…”
