Atomic structure of saturated chlorine monolayer on Ag(111) surface

Equilibrium geometric structure and electronic properties of Cl and H2O co-adsorption on Fe (100) surface

“…The discussion above implies that Cl intensifies the interaction of H 2 O molecules with substrate Fe atoms. Such results are similar to the results of Cl and Br co-adsorbed with H 2 O molecules on Ag (110) surfaces [31][32][33][34][35][36] .…”

Theoretical study of chlorine adsorption on the Ag(111) surface

“…Scanning tunneling microscopy experiments have been interpreted as a parallel double row structure, where Cl atoms occupy bridge and threefold hollow sites, 8 or as a (17ϫ17) overlayer at saturation. 4 A structural determination with SEXAFS gave a Ag-Cl bond length of 2.70Ϯ0.02 Å at a nominal coverage of 1/3 of a monolayer and 2.70Ϯ0.01 Å at a nominal coverage of 2/3 of a monolayer. 6 Cl was found to adsorb in threefold hollow sites in a ͱ3ϫͱ3R30°pattern; for the higher coverage a vacancy honeycomb structure was proposed.…”

“…The adsorption of chlorine on the Ag͑111͒ surface has been studied by various groups and with different techniques including low energy electron diffraction ͑LEED͒, [1][2][3][4][5] surface extended x-ray absorption fine structure ͑SEXAFS͒, 6,5 Auger spectroscopy, [1][2][3] thermal desorption, 1,3 measurements of adsorption isobars and isotherms, 7 work function measurements, 1 and scanning tunneling microscopy. 4,8 However, there is still an ongoing discussion about the correct interpretation of the experiments. Various explanations of observed adsorption patterns have been proposed, and the bond length has been measured twice with significantly different results.…”

Lateral interaction and structures in Cl adlayers on the Ag(111) surface

“…The maximal Cl coverage on Ag(111) was found to be of 0.55, and chlorine desorbs from the surface (at 650-780 K) as silver chloride clusters [3,16]. The low energy electron diffraction (LEED) study of Cl on Ag(111) [1][2][3][4][5], performed at room temperature, did not reveal the formation of ordered structures at low coverages. A well-defined LEED pattern appears only for the coverage slightly below saturation.…”

“…The importance of a detailed knowledge of mechanisms of the reaction has stimulated extensive studies of the structural and kinetic properties of chlorine layers adsorbed on various Ag surfaces . In particular, the adsorption of chlorine on the Ag(111) surface has been studied both theoretically and experimentally by different techniques including low energy electron diffraction (LEED) [1][2][3][4][5], surface extended X-ray absorption fine structure (SEXAFS) [5,14], Auger spectroscopy [1][2][3], thermal desorption [2,3], scanning tunneling microscopy [4,13,15], temperature programmed X-ray photoelectron spectroscopy (TPXPS) [16], and by DFT calculations [17][18][19][20][21][22].…”
