Figure 2

Imaginary (black) and real (red) part of the dielectric function and eels function (blue) for the systems studied in this work. From top to bottom: (a) clean ZnS, (b) Al:ZnS (Al content ≃1.6%) and (c) Cu:ZnS (Cu content ≃3.2%). Only the results for the zincblende host lattice are shown, as the wurtzite case presents only minor modifications.
