“…In this work, CBD is used due to the simple requirement, and reproducibility [11][12]. To change the structural, electronic and optical properties of CuO thin films, researchers either annealing or doped [13][14][15][16][17][18]. So, they added different features to CuO.…”

“…For example, Au was doped to CuO films to detect gases by Ando et al [19] and Proença et al [20]. The CuO films were annealed at a different temperature to fabricate the photovoltaic device, sensor, by Marzukil et al [13] and Gopalakrishana et al [14]. In this work, it was examined how the structural, optical and electrical properties of Au-CuO films changed with annealing.…”

In this work, the effect of annealing on Au-CuO films obtained by chemical bath deposition method was studied in terms of their structural, electrical and optical properties. Annealing process was carried out at an oxygen environment. The CuO peaks were detected using X-ray diffraction and all of the films were polycrystalline. Crystal size, preferential orientation, and surface tension were estimated from XRD data. The surface morphology and thickness of the films was determined using a field emission scanning electron microscope. Energy dispersive Xray analysis stated average atomic percentages of Au in the films. The electrical resistivity values of the films determined using four probe methods varied from 155.74 to 496.87 Ω.cm. The optical properties of the films were determined using the optic spectrometer. The energy band gap values, extinction coefficient, refractive index and dielectric coefficient of the films were also calculated.

In the present study, Cu2O films were deposited on a glass substrate via RF (radio frequency) magnetron sputtering under substrate temperature conditions that ranged from room temperature (RT, 25 °C) to 400 °C. The structural, compositional, and optical properties of the Cu2O films were analyzed in relation to the experimental variables by applying various measurement methods. The substrate temperature was a crucial factor in shaping the structural, compositional, and optical properties of the Cu2O films that were synthesized via RF-magnetron sputtering. Our findings revealed that the Cu2O films exhibited a cubic structure, which was confirmed by XRD analysis. Specifically, the (111) and (200) planes showed different trends with respect to the substrate temperature. The intensity of the (111) peak increased at 250 °C, and above 300 °C, the preferred orientation of the (111) plane was maintained. The grain size, which was determined via FE-SEM, displayed a positive correlation with the substrate temperature. Additionally, XPS analysis revealed that the binding energy (BE) of the Cu2O film sputtered at 400 °C was similar to that which was previously reported. Notably, the as-grown Cu2O film demonstrated the highest transmittance (15.9%) in the visible region, which decreased with increasing substrate temperature. Furthermore, the energy band gap (Eg) of the Cu2O films remained constant (2.51 eV) at low substrate temperatures (25 °C to 200 °C) but exhibited a slight increase at higher temperatures, reaching 2.57 eV at 400 °C.
