T a perfect 20BZY epitaxial film would develop on MgO, and to further push the lattice distortions toward tensile strain, we develop a buffer layer of 40 Ce-doped BaZrO3 (BZC) in situ involving the substrate and also the film. Below 800 , BZC has an orthorhombic cell having a pseudocubic lattice parameter of about four.3 [32] thus larger than either MgO or 20BZY. BZC can also be expected to be a very good electrical insulator inside the gaseous environment (humidified Ar) and temperature variety (600 ) where the proton conductivity is generally investigated. To very carefully tune the strain, the generation and evolution of your film strain (proportional towards the strain more than the elastic modulus) was monitored in situ having a multi-beam optical pressure sensor (MOSS) by measuring the change in substrate curvature (see Figure S1 within the Supporting Info). For all films, X-ray diffraction (XRD) confirmed the anticipated epitaxial in- and out-of-plane orientations (Figure 1). Only the (002) reflection of substrate and film plus the (001) reflection on the film, that is forbidden for the rock salt structure from the substrate, are visible in the out-of-plane measurement (Figure 1a). Ce-doped BaZrO3 (BZC) has a bigger lattice continual than BZY, consequently the BZC(002) reflection is clearly visible although the BZY(002) reflection is only discernible as a shoulder of the MgO(002) substrate reflection. The asymmetric (103) reflection on the film (forbidden for the substrate) is located at intervals of 90showing the cubic in-plane symmetry, aligned with all the substrate lattice (Figure 1b). The chemical composition of your films was analyzed with Rutherford backscattering and particle induced X-ray emission and found to be Ba0.98Zr0.82Y0.21O2.85 (see Figure S2 in the Supporting Data); hereafter, this composition is going to be referred to as BZY. It can be worth highlighting that such a somewhat compact Ba deficiency, which is frequently reported in literature for barium zirconate samples,[33] does not significantly have an effect on theAdv.

Electron diffraction (Figure 2b) did not reveal the presence of secondary phases or strongly tilted grains, along with the evaluation in the chemical profile demonstrated the absence of chemical inter-diffusion a.
