چکیده مقاله

In this paper, transparent conductive ZnS/Au/ZnS nano-multilayer films have been designed and the
optimum thickness of gold and zinc sulfide layers are calculated. The conductive transparent ZnS/Au/ZnS
nano-multilayer structure with optimized thickness have also been fabricated on a glass substrate by
thermal evaporation and have been annealed in air at different temperatures. The electrical, optical
and structural properties of the films such as electrical resistivity, optical transmittance, grain size have
been obtained. X-ray diffraction patterns show that increase in annealing temperature increases the
crystallinity of the structures. Moreover, Scanning electron microscope images of the samples show that
the grain sizes become larger by increasing the annealing temperature which is in consistence with the
X-ray diffraction analysis.
