Stability and role of zinc and sulfur atoms on the electronic properties and density of states of zinc sulfide during [H/OH] adsorption

Abstract

This research article wants to investigate the structural stability and electronic properties of Zinc sulfide (Zn ₁₄ S ₁₃ ) heterocluster through H ₂ O molecule adsorption using first-principles studies. A comprehensive investigation on H ₂ O grabbing by Zn ₁₄ S ₁₃ heterocluster was carried out using DFT computations at the CAM–B3LYP–D3/6–311+G (d, p) level of theory. The notable fragile signal intensity close to the parallel edge of the nanocluster sample might be owing to H ₂ O binding induced non-spherical distribution of Zn ₁₄ S ₁₃ heterocluster. The hypothesis of the energy adsorption phenomenon was confirmed by density distributions of TDOS/PDOS/OPDOS, and LOL for pristine and hydrated Zn ₁₄ S ₁₃ heterocluster. A vaster jointed area engaged by an isosurface map for H ₂ O adsorption on Zn ₁₄ S ₁₃ surface towards formation of hydrated Zn ₁₄ S ₁₃ complex due to labeling atoms of O1, Zn15, S27, H29, H30. Therefore, it can be considered that zinc in the functionalized Zn ₁₄ S ₁₃ might have more impressive sensitivity for accepting the electrons in the process of H ₂ O adsorption. It is considerable that when all surface atoms of Zn ₁₄ S ₁₃ are coated by OH and H groups, the semiconducting behavior is recovered. Our results open up the possibility of tailoring the electronic properties by controlling the surface adsorption sites.
