Abstract

In the present study, structural and physical
properties of the PbS thin films produced using chemical bath deposition method
were investigated.
Deposition temperature was varied between 25 °C and 50 °C throughout the deposition
period. The pH value of electrolyte solution and the deposition time of the
films were 10.5 and 25 min, respectively. Characterizations of the PbS thin films
were performed using scanning electron microscopy (SEM) and X-ray
diffraction (XRD) methods. XRD results showed
that all PbS thin films had a cubic structure irrespective of deposition
temperature. Morphological
characterizations of the films indicated that not only the number but also the
size of pinholes, formed on the film surfaces, were significantly affected by
the deposition temperature. Consequently,
the film obtained at 25 ̊C exhibited a surface morphology with less and smaller
pinholes, compared to others deposited at higher deposition temperatures.
