Moreover, the solute segregation behaviors at the stacking faults and their effects on stacking fault energies have been evaluated with a focus on the H-induced localized plasticity phenomenon, while H-X solute pair competitions in Ni has also been discussed in detail. Finally, the variations of shear moduli and stacking fault energies of Ni with the presence of interstitial solutes have been evaluated and their correlation has been proposed. The results revealed a strong effect of volumetric strain on interstitial solute segregation in Ni, while stacking faults acted as potential traps for interstitial solutes.

A systematic analysis of the structural, and optoelectrical characteristics across different applied discharge voltages aimed to establish connections between deposition parameters and film attributes. Experimental measurements utilizing instruments like the voltage divider, Rogowski coil current monitor, electron beam detector, and photomultiplier output recorded using a digital oscilloscope to assess plasma focus parameters. Copper oxide thin films were deposited on glass substrates using a plasma focus device, employing varied discharge power and an oxygen-helium gas mixture (50: 50 ratio) for deposition at 20 mTorr. Structural assessments employing X-ray diffraction (XRD) and scanning electron microscopy (SEM) unveiled voltage-induced alterations in crystallite size, orientation, and morphology, impacting the film's crystallinity and surface characteristics. Notably, increasing discharge power led to an enlargement of crystallite size from ≈14 nm to ≈18 nm. The direct energy band gap of the films was found to be decreased from 2.10 eV to 1.81 eV with an increase in the discharge power. In addition, the dielectric parameters were analyzed whereby it was found that the static refractive index n<sub>0</sub> and lattice dielectric constant <em>ε</em><sub>∞</sub> reduce with increasing the discharge power.
