摘要

Results of a high-resolution synchrotron photoemission study of sulfur adsorption on Cu(100) and Cu(111) surfaces are reported. Sulfur adsorption was performed by immersion of pristine samples into aqueous Na2S, which provokes strong sulfidation of copper. Annealing leads to partial elimination of S and progressive formation of well-ordered surface sulfur phases followed here by LEED. This translates into sizable Cu 2p core level binding energy (CLBE) shifts as well as changes in the S 2p binding energies.
