Microstructural and Optical Properties of Electrodeposited CdSnSe Thin Films

The various copper sulphate concentrations prepared CdS thin films were coated on glass substrates by chemical bath deposition. The structural, optical, functional group and morphological properties were studied using X-ray diffraction (XRD), UV-Vis-NIR spectrophotometer and scanning electron microscopy, respectively. The deposited films are found to be polycrystalline in nature with hexagonal structure along a (100) preferential orientation plane. The microstructural properties of CdS thin films such as crystallite size, micro strain, texture coefficient and lattice constant were calculated from structural studies and results are compared with earlier reports. The optical properties of CdS thin films band gap were lying between 2.38 and 2.49 eV. The stoichiometric composition with uniform surface morphological properties of the film was obtained in optimized molar concentration. The morphological images revealed that size of the grains was found to be 50 to 75 nm and some place group of grains agglomerate to form larger grains.

“…DMS materials, specifically binary semiconductors doped with transition metals, have emerged as promising candidates for applications in spintronic devices and thin film solar cells [ 1 ]. With an intrinsic bandgap of 1.74 eV, CdSe serves as a crucial platform for exploring the effects of dopants on its structural and optoelectronic properties [ 2 ]. In the synthesis of Iron (Fe) doped CdSe, the incorporation of nano-crystalline grains assumes significance.…”
