【 摘 要 】
A thin film of iron disulfide (FeS2) and Mn-doped was prepared using the chemical spray pyrolysis (CSP) method at a constant temperature of the glass substrate at around 400 °C. According to XRD examination, films were structurally cubic oriented with a predominant planar orientation (201). The doping of Mn ions in the FeS2 host matrix was confirmed by a minor shift of the diffraction peak towards the lower 2θ values. The surface of the produced film for pyrite was homogeneous, according to the AFM investigations. According to the XRD data, the predicted grain size altered as the consistent manganese increased. When compared to undoped FeS2 thin films, the Mn2+- doped FeS2 thin films' desired bandgap energy showed a red shift.
