چكيده فارسي :
ZnS film has been deposited on PbS buffer layer using thermal evaporation, the ZnS film has nanostructure (nanowires) due to effect
of PbS which play role of catalyst. This growth for non doped films have dense structure (for PbS and ZnS films). SEM morphology
of ZnS/PbS, ZnS and PbS have been studied in details (surface and cross section). Atomic force microscopy (AFM) used to
characterized the thins films (ZnS and PbS). X-ray photoelectron spectroscopy (XPS) and EDX techniques have utilized to know the
chemical and stoichiometry of deposited films. The crystallographic properties have been studied using XRD patterns, it found that
the results in Raman and XRD characterization have a good agreement. UV-Vis spectroscopy is used to acquire an idea about optical
properties of thin films deposited on glass substrate. The deposited ZnS nanowires and thin film have hexagonal phase, which
indicate to the buffer layer, which does not affects the structural but changes the growth mechanism. High Resolution Transmission
Electron Microscope (HRTEM) images have confirmed the formation of ZnS nanowires..
