Summary: This paper presents the preparation of Sn doped ZnO thin films using a low-cost chemical sol-gel spin coating process and the deposition of Ohmic and Schottky electrodes to form a Metal-Semiconductor-Metal (MSM) structure. The UV detection capability of the device was analyzed through electrical characterization, and various parameters including saturation current, ideality factor, and barrier height were calculated. The results showed an increase in forward and reversed bias current when exposed to UV light, and the responsivity and series resistance of the device were also reported.

Summary: This paper introduces a method to enhance the sensitivity of a p-type metal oxide semiconductor gas sensor to NO2 gas by decorating CuO nanowires with ZnO nanoparticles. The CuO/ZnO gas sensor showed better sensitivity to NO2 gas compared to the pristine CuO gas sensor. The study demonstrated that adjusting the width of the HAL could improve the NO2 sensing characteristics of the gas sensor.

Summary: Doped ZnO nanoparticles were synthesized using sol-gel method with simultaneous incorporation of Gallium (Ga) and Indium (In). XRD analysis indicated pure hexagonal wurtzite structure, and different dopant ratios led to significant variations in crystallite sizes. Co-doped samples exhibited higher reflectance in the visible region compared to undoped and single doped samples.

Summary: TiO2/ZnO nanocomposites with different Ti/Zn ratios were successfully synthesized by sol-gel and hydrothermal methods, exhibiting excellent photocatalytic performance. The degradation rate of methylene blue by TiO2/ZnO nanocomposites with a Ti/Zn ratio of 2:1 was close to 100%, outperforming other samples. The improved catalytic performance was attributed to the ability to separate holes and electrons.

Summary: The sol-gel method was used to fabricate Al-doped ZnO (AZO) thin films on p-Si substrates with smooth surfaces and highly oriented crystal structures. The analysis revealed that the AZO/Si heterojunctions exhibited nonideal diode behavior, with the 80 nm thick AZO layer demonstrating good rectifying properties.

Summary: Metal oxide semiconductor materials have shown great potential in heterojunction thin film fabrication for photovoltaic mechanism improvements. The development of a p-(111)-Cu2O heterostructure with a uniform and highly oriented n-TiO2/(002)-ZnO bilayer thin film successfully addressed electron mobility issues. By utilizing sol-gel spin coating method to deposit the n-TiO2/ZnO bilayer as a window layer, improvements in crystalline size and transmission spectrum were achieved.

Summary: In this study, ZnFe2O4@ZnO-N/B/RGO and ZnFe2O4@ZnO-C3N4 ternary heterojunction nanophotocatalysts were successfully prepared via sol-gel technique, demonstrating significantly improved photocatalytic properties compared to bare ZnFe2O4 and ZnO, especially in the degradation of methyl orange under UV and visible light irradiation. The ternary heterojuncted ZnFe2O4@ZnO-N/B/RGO was found to absorb lower energy visible light wavelengths, enhancing the photocatalytic properties of ZnFe2O4@ZnO loaded on reduced graphene oxide (RGO) nanosheets and graphite-like carbon nitride (g-C3N4), providing photo-Fenton degradation properties for the catalyst.

Summary: This study presents the fabrication and electrical analysis of a ZnO nanostructure-based Schottky device using a cost-effective method. The Ni/ZnO junction annealed at 400oC with silver probing resulted in the formation of a metal-semiconductor-metal back-to-back Schottky diode, which exhibits rectifying properties. The electrical parameters of the device have been determined based on the thermionic emission mechanism and the BBSD model.
