SrTiO3(001) surface structures under oxidizing conditions
نویسنده
چکیده
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 defects in a form of subsurface voids. The consistency and high reproducibility of our results suggest construction of a phase diagram for the formation of different structures on the SrTiO3(0 0 1) surface as a function of annealing temperature. 2002 Elsevier Science B.V.

We report the solution of the c(4 × 2) reconstruction of SrTiO3 (001), obtained through a combination of high-resolution transmission electron microscopy, direct methods analysis, and density functional theory. The structure is characterized by a single overlayer of TiO2 stoichiometry in which TiO5 polyhedra are arranged into edge-shared structures, in contrast to the corner-shared TiO6 polyhed...

The structural characteristics of SrRuO3 thin films deposited on a (001) SrTiO3 substrate by pulsed laser were studied by transmission electron microscopy (TEM) and high-resolution TEM. TEM studies of cross-sectional specimens revealed the epitaxial growth of the films with the SrRuO3-(110) plane parallel to the SrTiO3-(001) plane. Two types of 90° rotational domain structures were observed in ...

Several such stabilization mechanisms are explored via a combination of theoretical and experimental methods. The ...
متن کاملNanoscale Structure and Morphology of Atomic Layer Deposition Platinum on SrTiO3 (001)
The early stages of nucleation and growth of atomic layer deposition (ALD) platinum on SrTiO3 (001) have been studied. Scanning electron microscopy reveals the ALD Pt deposits as discrete nanoparticles that grow and coalesce with increasing number of ALD cycles, ultimately resulting in a continuous film after ∼40 cycles. Atomic force microscopy shows the films to be fine-grained and highly conf...
