Abstract
We report a scanning tunneling microscopy (STM) study of formic acid adsorption on clean Cu(110) at 300 K. An ordered structure was observed consisting of short rows parallel to the [11-bar0] direction, with an inter-row spacing in the [001] direction of two lattice spacings of the unreconstructed (1×1)-Cu(110) termination. Adjacent domains of this structure were offset in the [001] direction by one lattice spacing giving relatively short-range order in the [11-bar0] direction. A structure is proposed to account for the observed STM images.Keywords
