Laser microscope profilometry of SrTi0.3Fe0.7O3-d electrode surface after quickly drying

The dataset consists of a surface image, topography and profilometry obtained using a Keyence VK-X1000 confocal laser microscope for SrTi0.3Fe0.7O3-d electrode (STF70). Imaging was performed to determine surface roughness. The Keyence VK-X1000 uses a 404 nm laser to map and measure the surface of samples via confocal scanning or a wide-field variable focus. The analyzied STF70 electrod was quickly dried (120 C for 20 min) after screen printing on polished CGO-20 substrate. The examination revealed the existence of surface cracks.
