Effect of Annealing Temperature and Film Thickness on the Optical properties of CuInSe2Thin Films
Elharari, Najah Ibrahem; Magrem, Amna Abo; Trab, Sumaya Faraj (جامعة الزاوية, 2021-09)The researcher prepared CuInSe2 thin films by conventional evaporation method under vacuum . And he also prepared films at different film thickness and different annealing temperatures. X-ray diffraction indicates that the ... -
EFFECT OF REPLACEMENT OF THE Cu VITAL ENVIRONMANT FOR La ON THE TRANSPORT PROPERTIES OF YBa2(Cu x-1 Lax)3O -7
Abdulqader, Sanaa Masod; Elharari, Najah Ibrahem; Ali, Saad Salem Saad (مجلة كليات التربية, 2021-11)To be able to produce high quality superconducting material, the effect of substitution of copper in YBa2(Cu x-1 Lax)3O -7 δ superconductor by La content ( x=0 – 0.06 ) have to be understood . The study of transport ... -
Exploring the resonant vibrational excitation levels of hydrogen at border angles [0º-180º] by observing the differential cross sections
Elharari, Najah Ibrahem; ABDULQADER, SANAA MASOD ALMUKHTAR; ALI, Saad Salem Saad (جامعة الزاوية, 2021-09)In this research, the experience of exploring the vibrant levels of vibration for hydrogen, through the monitoring of differential sections, was used for the modified cross-brochield. The experiment begins by extracting ...
