Fig. 7: Structural model of water adsorption on 2D MoSH surface, density of states and corresponding charge density difference profile.

a Lowest energy configuration of H2O adsorption, (b) projected density of states and (c) the corresponding charge density profile for H2O adsorbed with top and side view on 2D MoSH monolayer. The charge accumulation and depletion regions are represented by yellow and blue color, respectively, and 2 × 10−3 e/Å−3 has been set as the isosurface value.
