AbstractThis research is devoted to the effect of investigation of the ZnO content on the structural and electrical properties of (NiO)1-x (ZnO)x films prepared by pulsed laser precipitation on the glass substrate at room temperature. Thin-film (NiO)1-x (ZnO)x sediments were deposited with different composition ratios where x = 0, 0.2, 0.4, 0.6 and 1.0 with a thickness of n150nm. The diffraction pattern for X-ray analysis reveals that the structure of the prepared thin films is identical with the cubic phase and hexadecimal stage of x = 0 and 0.1, respectively while the structure is mixed with the remaining x value from both stages. It involves studying the conductivity versus temperature to estimate conduction mechanisms and the Hall effect for determining type and carrier concentration as well as movement values. The results showed that there are two connection mechanisms and thus activation energies. Hall Effect showed that most of the prepared thin films were converted from type p to n of type x at = 0.2 and 1.0. Concentration of the carrier increases twice the volume while the mobility decreases by two degrees of volume by increasing the ZnO content from 0.0 to 1.0. The results were explained in terms of variation in the size of the crystals by increasing the ZnO content in the prepared thin films.

AbstractIn this study, the melting-cooling method was used to prepare the chalcogenide compound S60-Se40-X-PbX. Four samples were obtained by partial replacement of Selenium with Lead in the weight ratios x = 0, 10, 20, and 30, respectively. The materials were mixed separately, ground, placed in quartz ampoules, and heated to 500 degrees Celsius. After conducting several operations on the samples, their insulating properties were studied, represented by the real dielectric constant and the imaginary dielectric constant, and the electrical conductivity was measured as a function of the frequency. It was found that partial replacement plays an impo ... Show More

AbstractThis study includes the manufacture of four ternary alloys represented S60Se40-XPbX with weight ratios x = 0, 10, 20, and 30 by the melting point method. The components of each alloy were mixed separately, then placed in quartz ampoules and vacuumed out with a vacuum of roger that 10−4 Torr. The ampule was heated in two stages to avoid sudden dissipation and precipitation of selenium on the inner mass of the quartz tube. The ampoule was gradually heated and kept at 450°C for approximately 4 hours followed by 950°C for 10 hours.at a rate of 10 degrees Celsius, the temperature of the electric furnace ... Show More

AbstractThe compound Fe0.5CoxMg0.95-xO where (x= 0.025, 0.05, 0.075, 0.1) was prepared via the sol-gel technique. The crystalline nature of magnesium oxide was studied by X-ray powder diffraction (XRD) analysis, and the size of the sample crystals, ranging between (16.91-19.62nm), increased, while the lattice constant within the band (0.5337-0.4738 nm) decreased with increasing the cobalt concentration. The morphology of the specimens was studied by scanning electron microscopy (SEM) which shows images forming spherical granules in addition to the presence of interconnected chips. The presence of the elements involved in the super ... Show More
