Effects of different deposition conditions on the properties of Cu₂S thin films

Effects of Deposition Time And PH on The Characterization of Chemically Synthesized Composite Nano-Wires of Cu2S Thin Films

“…Increasing the deposition time from 4 to 10 hours cause a reduction in the energy bandgap from 3.04 to 2.78 eV and this is shown in figure 11. These decrease in the energy gap of the Cu2S thin films may be attributed due to the transition from a poor crystalline to a polycrystalline state (Kırmızıgül et al, 2013) or the film composition (Isac et al, 2013). The obtained energy gap values are approximately the same values obtained by (Ismail et al, 2020). )…”

“…Besides, it has a limitation regarding the temperature of deposition. The temperature is normally restricted to about (100 °C), the inefficiency of the process, in terms of the utilization of starting materials and their conversion to thin films, the generation and disposal of large quantities of hazardous waste (Hodes, 2002;Lee, 2007), inadequate mixing of the reactants, and lack of control over reaction processing time (Kırmızıgül et al, 2013). Many parameters have to be noticed during the deposition process by CBD technique such as deposition time, bath temperature, pH value, and chemical reagents because they have a great effect on the deposited thin films' properties.…”
