Abstract

SnS thin films doped with two atomic % Ag are deposited on a pyrex glass substrates using chemical bath deposition method. The impact of 2 atomic % silver doping on the physical properties of SnS thin films is studied. X-ray diffraction studies confirmed that the deposited SnS films were of α-SnS phase with an orthorhombic crystal structure, which remained stable despite the addition of 2 at.% silver. It is observed that the addition of 2 atomic % silver to SnS chemical bath solution does not greatly influence the structural properties of SnS thin film. The deposition is carried out at different bath temperatures from 50℃ to 80℃. Additionally, structural parameters such as crystallite size, dislocation density, and lattice strain were analyzed, offering deeper insights into the quality and structural properties of the SnS films.
