Kimyasal Banyo Biriktirme Yöntemiyle Elde Edilen İğne Deliksiz PbS İnce Filmler

Abstract

In this study, the (Lead Sulfide) PbS thin films with one, two, and three layers were fabricated by employing the chemical bath deposition method. Layer by layer production of PbS thin films was realized for the first time as seen in the literature review. For investigating the crystal structures, the X-ray diffraction (XRD) analysis was used. The structural analyses indicated that the crystallite size was decreased from about 40 nm to 8-10 nm depending on the number of layers. The surface micrographs of the films were obtained using scanning electron microscopy (SEM). When the PbS film was obtained in one layer, some cracks, pinholes, and voids were observed on the sample surface. However, no cracks, voids, or pinhole formation were found on the film surface when the films were coated in two and three layers.
