Composite Nano-Structures Controlled by Weak Interaction on Solid Surfaces

Nano-materials and nano-composites formed on solid surfaces are discussed. (1) (–Cu–O–) strings and square shape (Cu2)3 dots on Ag(110), (2) unfixed shape nano-size Ni-islands on a Cu(100)–O surface covered with nano-size c(2×2)–O domains, and (3) nano-width wire and nano-size dots controlled by template of super structures; nano-width Ni-wires on a \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $${\text{(2}}\sqrt {\text{2}} \times \sqrt {\text{2}} ){\text{R45Cu(100)}}--{\text{O}}$$ \end{document} surface, nano-size Ni-dots on a Cu(100) surface covered with regularly arrayed nano-c(2 × 2)–N patches, and the supra-honeycomb layers composed of Zn3 on a reconstructed Si(111)-7 × 7 surface. We could say that weak adsorbate–adsorbate interaction plays an important role for nano-size self-assembly.
