Zusammenfassung
We present a new polymorph of the two-dimensional (2D) silica film with a characteristic ‘zigzag’ line structure and a rectangular unit cell which forms on a Ru(0001) metal substrate. This new silica polymorph may allow for important insights into growth modes and transformations of 2D silica films as a model system for the study of glass transitions. Based on scanning tunneling microscopy, low energy electron diffraction, infrared reflection absorption spectroscopy, and X-ray photoelectron spectroscopy measurements on the one hand, and density functional theory calculations on the other, a structural model for the ‘zigzag’ polymorph is proposed. In comparison to established monolayer and bilayer silica, this ‘zigzag’ structure system has intermediate characteristics in terms of coupling to the substrate and stoichiometry. The silica ‘zigzag’ phase is transformed upon reoxidation at higher annealing temperature into a SiO2 silica bilayer film which is chemically decoupled from the substrate.
