Chlorine Adsorption on Au(111): Chlorine Overlayer or Surface Chloride?
We report the first scanning tunneling microscope (STM) investigation, combined with density functional theory calculations, to resolve controversy regarding the bonding and structure of chlorine adsorbed on Au(111). STM experiments are carried out at 120 K to overcome instability caused by mobile s...

STM experiments are carried out at 120 K to overcome instability caused by mobile species upon chlorine adsorption at room temperature.
