Comparison of the structure, electronic, and optical behaviors of tin-doped CdO alloys and thin films
Spray pyrolysis technique (SPT) was applied to fabricate CdO films doped with tin at (0–8%) concentrations on glass substrates. Structural, morphological, and optical behaviors were inspected using X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV–Vis spectroscopy. Structural, elec...

alloys were studied in pseudo-potential method using density functional theory (DFT) in scissors approximation. The calculated electronic band structure and optical behavior were achieved in this work. Optical bandgap energy was found to increase from 2.581 to 2.943 eV via increasing Sn content, while theoretically, it was found to increase from 2.884 to 3.106 eV with the increasing Sn doping. Theoretical and experimental findings were close to each other. The linear energy-dependent dielectric functions (real part) and optical behavior-like absorbance and transmittance were also studied. |
