N2 - Sputtered thin Zinc sulfide (ZnS) films are dielectrics in the IR and THz ranges. Because of high refractive index and low absorption in the THz range, ZnS films are used as covering dielectric layers of conducting surfaces in the THz plasmonics. To develop plasmonic methods for a surface diagnostics, ZnS films can be used as reference films; therefore, it is important to know their optical properties. The optical constants for bulk ZnS are presented in the reference literature, but there are no data for thin layers. Besides, the structure and homogeneity of films can be significantly depend on sputtering technique, conditions, substrate material and the surface preparation method. In this work mid-infrared and THz optical properties of ZnS sulfide films with about 1-3 mm thick sputtered on different substrates (quartz, silicon, gold layers) with electron beam evaporation were studied using by THz time-domain spectroscopy, ellipsometry and spectrophotometry. Their surface roughness and homogeneity were tested with electron and atomic force microscopy.
