We employ SrTiO3 nanocuboid single crystals with well-defined (001) surfaces that are synthesized to have either a TiO2- or SrO-terminated surface to investigate the influence of surface termination on the morphology and the chemical property of supported metallic nanoparticles. Using such monodispersed STO nanocuboids allows for practical catalytic reaction studies as well as surface studies comparable...
Atomic surface structures of nanoparticles are of interest in catalysis and other fields. Aberration-corrected HREM facilitates direct imaging of the surfaces of nanoparticles. A remaining concern of surface imaging arises from beam damage. It is important to identify the intrinsic surface structures and the ones created by electron beam irradiation in TEM. In this study, we performed aberration-corrected...
Scanning tunneling microscopy study showed that the (2×2) reconstruction on the (001) surface of SrTiO 3 should have a surface structure with a 4-fold symmetry. The previously proposed solution for the (2×2) reconstruction with the p2gm symmetry only has a 2-fold symmetry. In this study density functional theory study was carried out to propose a possible surface structure with the p4mm surface...
