The surface structure of Cu(100) after chlorine adsorption and thermal desorption in ultrahigh vacuum is studied by STM. In both adsorption and desorption regimes the presence of adsorbed chlorine is not detectable by STM at coverages smaller than a full monolayer. We report for the first time atomic-resolution STM images of the Cu(100)-c(2X2)-Cl phase, and we show that the growth of a thicker chloride phase at room temperature occurs through the formation of multiatomic layer islands. © 1995 American Institute of Physics.
