摘要：

The structure of disordered chemisorbed sulfur overlayers on Cu(111) have been investigated using normal incidence X-ray standing, wavefield absorption (NIXSW). The NIXSW data indicates that within the coverage range studied, 0.13 < 0 < 0.30 ML, all the disordered layers contain the same structural sub-units. The NIXSW data are consistent with a previously proposed model, which suggests that at room temperature the disordered layers contain both sulfur adatoms and mobile CU3S3 clusters.
