“…The only difference lies in the existence of the La 3+ species at 835.1, 838.9 / 852.4, 856.1 eV standing for the LaAP phase in Fig. 5(a), which is consistent with the values of 833.9, 838.4 / 850.7, 855.1 eV reported by Haasch et al [27]. The species determined from their binding energies in both cases are consistent with the SEM-EDS results.…”

“…4) of Sr exhibits two peaks at around 133.7 eV and 135.4 eV which correspond to the 3d 5/2 and 3d 3/2 electron orbit of Sr 2+ . Two peaks of Ti2p located at 458.0 eV (2p 3/2 ) and 463.8 eV (2p 1/2 ) are observed, which belong to Ti 4+ in SrTiO 3 [12,29] , while no signal of Ti 4+ from TiO 2 is detected due to the full covering of Sr 1δ TiO 3 nanosheets. Based on all the results above, the tentative formation mechanism of SrTiO 3 microcubes and nanosheets is proposed (Fig.…”

As a perovskite family member, SrTiO 3 shows significant applications in the fields of solar cells, photocatalysis, fuel cells and superconducting as a dependence of its crystallinity, morphology, crystal facet and optical properties. In this work, we reported an in-situ synthetic approach of SrTiO 3 nanostructures with modified morphology and tunable optical absorption properties based on conventional plasma electrolytic oxidation (PEO) associated with hydrothermal method. The morphology of SrTiO 3 nanostructures can be selectively modified from microcubes with smooth facets to ultrathin nanosheets by controlling the concentration of Sr source during PEO process. It is found that both SrTiO 3 microcubes and Sr 1-δ TiO 3 nanosheets are well-crystallized single crystals. UV-Vis diffuse reactance spectrum (DRS) measurement reveals that Sr 1-δ TiO 3 nanosheets with thin thickness show obvious blue-shift of absorption edge in comparison with SrTiO 3 microcubes due to the size effect. Finally, the morphology evolution and nucleation mechanism of SrTiO 3 nanostructures in-situ grown on PEO film is discussed.

Symmetry-aware recursive image similarity exploration for materials microscopy

et al. 2021

In pursuit of scientific discovery, vast collections of unstructured structural and functional images are acquired; however, only an infinitesimally small fraction of this data is rigorously analyzed, with an even smaller fraction ever being published. One method to accelerate scientific discovery is to extract more insight from costly scientific experiments already conducted. Unfortunately, data from scientific experiments tend only to be accessible by the originator who knows the experiments and directives. Moreover, there are no robust methods to search unstructured databases of images to deduce correlations and insight. Here, we develop a machine learning approach to create image similarity projections to search unstructured image databases. To improve these projections, we develop and train a model to include symmetry-aware features. As an exemplar, we use a set of 25,133 piezoresponse force microscopy images collected on diverse materials systems over five years. We demonstrate how this tool can be used for interactive recursive image searching and exploration, highlighting structural similarities at various length scales. This tool justifies continued investment in federated scientific databases with standardized metadata schemas where the combination of filtering and recursive interactive searching can uncover synthesis-structure-property relations. We provide a customizable open-source package (https://github.com/m3-learning/Recursive_Symmetry_Aware_Materials_Microstructure_Explorer) of this interactive tool for researchers to use with their data.
