RETRACTED: Tunable electronic and optical properties of 2D PtS2/MoS2 van der Waals heterostructure (Retracted article. See vol. 139, 2022)

Dispersion corrected density functional calculations have been performed to investigate the electronic and optical properties of PtS2/MoS2 van der Waals heterostructures with four different stacking symbolized by AA, BB, AB, and BA. Our investigation affirms that the PtS2 monolayer can unshakably contact with MoS2 monolayer according to the calculations of binding energies and form four stable heterostructures. Also, it is disclosed that the PtS2/MoS2 heterostructures are semiconducting materials with band gaps between 0.323 eV (AB) and 0.664 eV (AA). Grippingly, it is expected from the computed optical properties that the PtS2/MoS2 heterostructures have the ability to absorb the light extensively ranging from infrared to ultraviolet regions. Consequently, the PtS2/MoS2 heterostructures are to be a promising candidate for visible light driven photovoltaic and photocatalytic devices. Finally, our proposition that the PtS2/MoS2 heterostructures, with unexpected excellent properties, can be benefited with different stacking in solar cells, field-effect transistors, catalysis, and optical devices.
