Electronic and optical properties of 2D graphene-like ZnS: DFT calculations

- DFT has been applied to investigate the optical properties of 2D-ZnS and 3D-ZnS.
- The electronic and the optical properties of 3D-ZnS and 2D-ZnS are compared.
- At visible range of energies the transparency of 2D-ZnS is more than the 3D.
