2021, Materials Today NanoCitation Excerpt :The as-received STO substrate surface terminates with either SrO or TiOx terraces that are distributed randomly, as depicted in Fig. 1a [43]. Undergoing an annealing process allows a surface reconstruction, and was first observed based on regional Sr enrichment [44]. It was later proven to result from the alternative arrangement of TiOx and SrO strips [45], with the majority being TiOx strips, as demonstrated by the 3D schematic diagram shown in Fig. 1c and tomography image measured by atomic force microscopy in Fig. S1a.

Adsorption of CO and formation of carbonates at steps of pure and Co-doped SrTiO <inf>3</inf> surfaces by DFT calculations
2016, Applied Surface ScienceCitation Excerpt :This versatility is largely due to the wide range of possible stoichiometries, and is further increased by the possibility of doping with d- and f-block elements [1]. SrTiO3 is a prototypical perovskite with relevant photocatalytic properties which can be used as a substrate to grow oriented thin films of superconductors [2–4] and as insulator for tunneling devices [5]. Furthermore, SrTiO3 can be used to obtain ferromagnetic doped systems with in-plane magnetic anisotropy [6], high temperature oxygen sensors [7] or capacitors and in dielectrical components [8,9].
