In this study, the ZnxCd1-xS ternary compounds are prepared as thin films on a glass slide substrate at 350 °C using a spray pyrolysis technique. Using X-ray diffraction to examine the films' structure, it was possible to determine that they were polycrystalline. The hexagonal crystal structure of films with x up to 0.4 in ZnxCd1–xS has been found...

This article presents a systematic technique for designing a novel multiband plasmonic antenna based on graphene with a silicon nitride (SiO3N4) dielectric substrate in the terahertz band frequencies. Higher conductivity values are found in the 1–5 THz ranges when the graphene conductivity values are measured at these band frequencies. Based on thi...

Titanium dioxide nanorods were prepared by hydrothermal method using titanium tetrachloride TiCl4 as a precursor solution and an expanded gate field effect transistor's (EGFET) sensing membrane has been used for pH sensing applications. The TiO2 nanorods were grown onto fluorine-doped tin oxide FTO coated glass substrates at a hydrothermal reaction...

In this study, the hydrothermal method is used for growing and characterization of titanium dioxide (TiO2) nanorods on the fluorine-doped tin oxide (FTO) substrate at different hydrothermal reaction temperatures and constant reaction time. The objective of the study is to investigate the effect of hydrothermal growth temperatures and annealing temp...

The fabrication of cobalt oxide (Co3O4) thin films has received considerable attention. The crystalline quality of Co3O4 plays an important role in the properties of the fabricated film. This paper reports on the performance of a local electrostatic spray pyrolysis system to prepare Co3O4 thin films on glass substrates. The effect of applying an el...

The Nd3+/Er3+ ions co-doped in the system of zinc-tellurite with the composition of (70-2x)TeO2-30ZnCl2-xNd2O3- xEr2O3 concentration from 1.0 to 3.0 mol% (x=1, 2 and 3) glasses were prepared by using conventional melt-quenching technique. The amorphous nature of the glass been confirmed by using X-RAY Diffraction Spectroscopy. Thermal characteristi...
