Journal of Physics: Condensed Matter is currently collating a Special Issue on the fundamentals of chemical functionalities at oxide interfaces, with the help of guest editors Stefano Agnoli and Matthias Batzill. This weeks image comes from one such paper by Svetlozar Surnev et al. investigating the properties of 2D ternary oxides on Pd (100) surfaces.
The authors synthesized MnWO x and FeWO x nanolayers using a solid state chemical reaction on Pd surfaces. They then determined their structure and stoichiometry with state of the art surface techniques including scanning tunnelling microscopy (STM), x-ray photoelectron spectroscopy (XPS) and high-resolution electron energy loss spectroscopy (HREELS).
The authors revealed that the nanolayers’ structure and composition vary strongly with the oxygen chemical potential: from an oxygen-rich layered hexagonal phase, weakly coupled to the substrate, to oxygen-poor bilayer commensurate structures, strongly bound to a Pd–Mn(Fe) alloyed interface.
