Abstract

Optical and structural characterization of ZnS thin films grown by chemical bath deposition (CBD), introducing for the first time a magnetic field (MF), are reported. Corning glass as well as Si and GaAs single crystals were used as substrates. The effect of H₂-annealing, in the range of temperature 200-300 °C, and MF on the morphology and crystalline structure of films is studied in atomic force microscopy images and in X-ray diffractograms. MF does not manifest appreciable influence on the grain size (GS) when glass substrates are used. On the contrary GS diminishes noticeably when MF is applied on ZnS/Si and ZnS/GaAs CBD-growths. Further, an improvement of the optical properties with post-growth annealing in H₂, as exhibited by optical transmission, is obtained. An application of these ZnS films as antireflective coating is analyzed by reflectance spectra.
