Optimization of Bi2O3, TiO2, and Sb2O3 Doped ZnO-Based Low-Voltage Varistor Ceramic to Maximize Nonlinear Electrical Properties
In ZnO-based low voltage varistor, the two essential features of microstructure determining its nonlinear response are the formation Bi-enriched active grain boundaries as well as a controlled ZnO grain size by secondary spinel-type phases. Besides, the microstructure and phase composition are strongly affected by the dopant concentration during sintering process. In this study, the optimal dop...

متن کاملSynthesis of ZnO/Bi2O3 and SnO2/Bi2O3/Bi2O4 mixed oxides and their photocatalytic activity
In the present work, ZnO/Bi2O3, SnO2/Bi2O3/Bi2O4 mixed oxide, Bi2O3 rod-like and SnO2 nanoparticle have been synthesized. The obtained samples were characterized by field emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD). The optical properties of samples were evaluated by UV-Vis spectrophotometer. The photocatalytic activity of samples was evaluated by decolorization o...
متن کاملGrowth and Electrical Properties of Doped ZnO by Electrochemical Deposition
In this work, pure and different metal ions doped ZnO thin films were obtained by a facile electrochemical deposition process. Different morphologies of ZnO, such as nanoplates, nanoparticles, as well as dense film can be obtained by doping Cu, In, and Al, respectively. Besides, the electrical properties of ZnO were also dependent on the doping ions. In this work, only pure ZnO shows resistive ...
متن کاملElectrical Properties of p-Si/n-ZnO Nanowires Heterojunction Devices
This paper explores the temperature dependent h terojunction beh vi r of n-type zinc oxide (ZnO) nanowires/pSi diodes. The device behavior at different temperatures in forward as well as reverse biased conditions are studied and reported. From the detailed electrical properties, it is confirmed that the fabricated p–n diode showed a good stability over the temperature range of 25–130 C. The tur...
