Abstarct: In this experimental research work we have studied morphological, structural, optical and electrical and thermoelectrical properties of nanostructured thin laxyers of pure copper sulfide (CuS) in various conditions by spray pyrolysis method. In this study we have used various apparatus for the physical characterization of the grown samples. These are including: we have used filed emission scanning electron microscope (FESEM), X-ray Diffraction (XRD), UV-Vis.-NIR spectroscopy, I-V measurement, and also Hall effect and Seebeck effect experiments. In fabrication of CuS samples we have used copper acetate (Cu(CH3COO)2•H2O) powder (as the copper source) and thiourea - CS(NH2)2 - (as the sulphur source). Through this investigation various parameters were investigated. These parameters are including: the precursor spray rate, variations of copper acetate concentrations plus annealing the samples in the presence of Ar-gas atmosphere, variations of thiourea concentrations, and finally the effect of two other copper source material including: copper chloride (CuCl2) and copper sulphat (CuSo4).
