Abstract:
In this research, thin films were prepared for nanocomposite materials deposited on quartz substrates by the pulsed laser deposition (PLD) method. The percentage of copper in the target material (3, 5 and 7%), the laser energy (600, 700 and 800 MJ) and the substrate temperature were used. (200, 300 and 400 Cᵒ) as variables for this technique. The design of experiments (DOE) using Taguchi was used, which designed (27) experiments according to these three factors. The prepared films were examined using (XRD, AFM, FESEM, EDX, Uv-Vis, Nanoindentation) to know The structural, optical and mechanical properties of the prepared thin film films and the knowledge of the optimum thin film using (Composite Desirability), which works towards increasing the hardness and reducing both the energy gap and the surface roughness and it was (11.23 Gpa, 2.79 ev and 1.25 nm) respectively , and (ANOVA) analysis showed that the most influential factor was In the results, the value is the percentage of copper in the target material..
The discussion of the dissertation was conducted in a scientific atmosphere and a master's degree with grade of pass was awarded to the student after the completion of all the corrections that have been decided by the examiners.
