Abstract

Water molecules adsorbed on metal surfaces can assemble into various H-bonding networks. Visualization of individual water molecules is one of the shortest route to clarify wetting processes on the surfaces ; however, in many cases, it remains difficult to identify the atomic configurations in the first water layers by scanning tunneling microscopy (STM) images alone. In this study, we observed one-dimensional water chains on Cu(110) by non-contact atomic force microscopy (AFM) with a probe tip terminated by carbon monoxide. Oxygen skeletons in the AFM images reveal the local structures in the water chains at high spatial resolution beyond STM. Therefore, AFM is an alternative option for characterization of water assembles on surfaces.
