Co-adsorption of water and glycine on Cu{110}

Abstract

In this study, we use density functional theory (DFT) to investigate the surface co-adsorption of glycine with water on Cu{110}. Our results show that, under UHV conditions and for a wide range of temperatures, a pure glycine monolayer is more stable than either mixed gly–water phases or pure water (ice) monolayers, but for a high water pressure half-dissociated water layers can appear on the surface at low and medium temperatures.
