Atomistic simulation of SrTiO3(001) surface relaxation
The (001) surface relaxation of the cubic perovskite SrTiO3 crystal has been studied using the shell model. The positions of atoms in several surface layers embedded in the electrostatic field of the remainder of the crystal are calculated. We show that Ti4+, Sr2+, and O2− ions in six near-surface layers are displaced differently from their crystalline sites which leads to the creation of so-ca...
متن کاملSrTiO3(001) surface structures under oxidizing conditions
The thermodynamically stable (2 1), c(4 2) and c(6 2) surface structures were obtained under oxidative conditions on the SrTiO3(0 0 1) surface and studied with transmission electron microscopy. All three reconstructed surfaces exhibit similar morphological features––formation of flat h100i facets on the surface, stabilization of h110i originally polar facets as well as the existence of surface ...

متن کاملMicroscopic characterization of Fe nanoparticles formed on SrTiO3(001) and SrTiO3(110) surfaces
Fe nanoparticles grown on SrTiO3 (STO) {001} and {110} surfaces at room temperature have been studied in ultrahigh vacuum by means of transmission electron microscopy and scanning tunnelling microscopy. It was shown that some Fe nanoparticles grow epitaxially. They exhibit a modified Wulff shape: nanoparticles on STO {001} surfaces have truncated pyramid shapes while those on STO {110} surfaces...
