摘要
STM and LEED techniques were applied to study the structure of saturated chlorine monolayer formed on Ag(111) as a result of Cl-2 adsorption at room temperature. We present for the first time atomic resolution STM images of chlorinated Ag(111) surface obtained in ultra-high vacuum conditions. The structure of chlorine layer was identified by means of a Fourier analysis of the STM images as Ag(111)-(17 x 17)-Cl. The structure of saturated chlorine monolayer remains unchanged for Cl-2 exposures up to 100 000 L and coexists with AgCl islands on Ag(111) surface. (C) 1998 Elsevier Science B.V.
