The authors have studied the adsorption of chlorine on the Ti(0001) surface using Auger electron spectroscopy (AES), low-energy electron diffraction (LEED), and thermal desorption spectroscopy (TDS). Chlorine overlayers were generated by using an electrochemical source of molecular chlorine at temperatures ranging from 30 to 600/sup 0/C. Adsorption is dissociative with an approximately constant sticking coefficient at low coverages. The adsorbed chlorine is sensitive to electron beam stimulated desorption (ESD) but does not thermally desorb below 750/sup 0/C. They did not observe any ordered LEED patterns unless a high-coverage surface was annealed to a temperature of 620/sup 0/C. The resulting complex LEED pattern suggests that the adsorbed chlorine forms a coincidence lattice on the titanium surface. The data is consistent with the formation of a pseudo-halide surface layer related to TiCl/sub 3/.
