Yttrium doped barium zirconate (BZY) thin films show promise thanks to their extremely high proton conductivities and their possibility for use in studying fundamental processes such as exsolution. This work reports on the decomposition of BZY thin films, resulting in highly oriented barium carbonate rods on the surface of the strontium titanate substrate. Characterization is performed, detailing the relation between the barium carbonate rods, zirconia particles, and the initial BZY thin film. Additionally, the causes and modes of decomposition in these thin films are discussed in detail.
