Crystal properties, morphological structure, phase structure, elemental contents and optical properties of Cu2SnS3 thin films have comprehensively been studied by XRD, SEM, Raman, EDX, UV-vis, and photoluminescence analysis, respectively. The crystalline size, dislocation density, microstrain and crystalline number of Cu2SnS3 thin films have been calculated. Cu2SnS3-A2 thin film annealed for 30 minutes has the best crystal structure. Cu2SnS3 thin films contain four different phases depending on sulphur flux rate and the annealing temperature duration. In addition, their band gaps, extinction coefficients and Urbach energies were determined. The refractive index and high frequency dielectric constant of Cu2SnS3 thin film were calculated using Herve and Vandamme, Moss and Ravindra relations and the values found were found to be compatible with one another. The skin depth and optical conductivity of Cu2SnS3 thin films were obtained. While the photon energy increased, their skin depth decreased and the optical conductivity considerably increased.eninfo:eu-repo/semantics/closedAccessCu2sns3Cts Thin FilmCrystalline SizeRefractive IndexSkin DepthArticle253-4191202WOS:0010319427000132-s2.0-8516287491810.1016/j.jssc.2021.122711Q4N/A
