Scheme of two-dimensional nanostructures at silica surface. (a) Uniform distribution of chemical composition and structure, for example, monolayers of element-oxygen groups of a given composition: () monolayer thickness; () total layer thickness, ; and (1) Ti-O monolayers. (b) Periodical distribution along the -axis of element-oxygen layers containing a certain number of monolayers: (1) Fe-O groups and (2) Ti-O groups ((A) two-layer structure, and (B) four-layer structure, and ). (c) Aperiodic distribution of element-oxygen layers along the -axis (four-layer structure with ). (d) Aperiodic atomic distribution in the surface monolayer plane (top view): (crosses) Fe-O groups and (circles) Ti-O groups ((A, B) different Fe-O/Ti-O ratios). (e) Aperiodic distribution of “zero-dimensional” structures in the substrate plane: (1) Fe and (2) Si.
