SnS thin films were grown by RF sputtering and $SnCl_2$ treatment was applied by wet chemical processing. While the samples grouped as $SnCl_2$ heat treated and annealed were subjected to annealing in air atm, the as-deposited sample was not applied any annealing process. The as-deposited sample grew in the orthorhombic SnS phase. Annealing of the SnS sample in air environment led to the formation of orthorhombic SnS as well as non-dominant $SnCl_2$ and $SnCl_2$ phases. It was found that applying $SnCl_2$ heat treatment to SnS deteriorated the crystallization and especially the $SnO_2$ oxide phase became more dominant. Raman spectra confirmed the presence of SnS and SnS2 phases in the samples, but no evidence of $SnO_2$ phase was found. SEM images showed bladelike, dense grain formation in the as-deposited and annealed samples. However, $SnCl_2$ heat treatment completely changed the surface morphology of the sample, causing it to transform into a structure consisting of several domains split by deep fractures. EDS revealed a distinct Sn-rich composition of the as-deposited and annealed samples (Sn/S~1.2). On the other hand, $SnCl_2$ heat treatment caused a massive loss of sulphur in the atomic distribution of the SnS and it was seen that the Sn/S ratio increased to around 7.5. The band gaps of the as-deposited and annelaed samples were calculated as 1.43 eV and 1.45, respectively. However, $SnCl_2$ heat treatment led to an increase to 1.56 eV of the band gap. Analysis results show that $SnCl_2$ treatment by the wet processing causes a significant change on the characteristics of SnS thin film. In this context, it can be said that $SnCl_2$ heat treatment can be further improved with optimization processes.eninfo:eu-repo/semantics/openAccessNanobilim ve NanoteknolojiKimyaUygulamalıMalzeme BilimleriÖzellik ve TestÇevre BilimleriMühendislikKimyaRF sputteringSnSair annealing$SnCl_2$ treatmentArticle12395796410.28948/ngumuh.12690371188239
