Figure 3.

Physical adsorption of WX₂Y₂ on the WS₂{010} facet at different −SH coverages, including vdW interactions. The surface is reduced from (a) to (d) by desorption of a H₂S molecule creating different −SH coverages. The reduction of the WS₂{010} surface makes precursor adsorption more favorable. This schematic corresponds to reactions 8–11 in Table 2. The color code and ligand abbreviations are the same as in Figure 2.
