Cobalt-doped ZnO (CZO) thin films were deposited on glass substrates at room temperature by radio frequency (RF) magnetron sputtering of a single target prepared with and Co3O4 powders. Changes in the crystallinity, morphology, optical properties, chemical composition CZO investigated various powers 45, 60, 75 W. All samples presented hexagonal wurtzite-type structure preferential c-axis (002) plane, along distinct change strain values through X-ray diffraction patterns. Scanning electron...
Metal oxide semiconductors (MOS) based gas sensors have been identified as a promising solution for future applications due to their exceptional electrochemical, physical, and sensing properties. Due excellent optical electrical features, ZnO nanostructures become increasingly popular detection applications, mainly because of abundant availability. Despite its potential, the ZnO-based challenges such poor selectivity high power consumption at elevated operating temperatures. Transition metal...
Worldwide atmospheric pollution is one of the biggest and deadliest issues as effect prolonged exposure to gases such nitrogen oxides (NO x ), carbon dioxide (CO 2 monoxide (CO) volatile organic compounds (VOC) cause severe adverse effects towards environmental human well-being [1]. Significant research efforts were made for development gas sensors that can precisely detect amount toxic present in air. Metal oxide semiconductors (MOS) are being intensively developed due their inherent...
Keywords: Ammonia, Electrospinning, and Zinc Oxide The matter of air pollution has dramatically risen the worldwide concern on detecting hazardous gases present in atmosphere because they are highly detrimental to human health [4,5]. Additionally, detection monitoring such harmful is necessary for process control industry as well general safety environment. oxide (ZnO) an n-type semiconductor with a wide direct bandgap width (3.37 eV), high excitation binding energy (60meV), electron...
