Rocking curves (ω-scan) of the symmetric BiVO4(004) peak for BiVO4films with varying thicknesses on YSZ substrates. The rocking curve of the symmetric YSZ(002) peak for the YSZ substrates is also shown. Thinner BiVO4films exhibit sharp rocking curves with FWHM values close to that of the substrate. A broad Gaussian background peak (FWHM ≈ 0.35–0.37°) emerges with increasing film thickness, suggesting a relaxation of the film. Note that the rocking curves are normalized and shifted for clarity.
