STUDY OF STRUCTURAL AND DIELECTRIC PROPERTIES OF COPPER OXIDE NANOPARTICLES PREPARED BY WET CHEMICAL PRECIPITATION METHOD [16] The DC conduction and dielectric behaviour of copper oxide nanoparticles prepared by sol-gel method and sintered at 950 °C were studied in the temperature range of 200–526 K. The formation of single phase monoclinic CuO was confirmed by x-ray diffraction. Wolhfarth, Ferromagnetic Materials, Vol. II, North-Holland, Amsterdam, New York, Oxford, Tokyo (1980). Penn, Phys.

Kavitha, AIP Conference Proceedings. Further, electronic properties like valence electron plasma energy, Penn gap, Fermi energy and electronic polarizability of the CuO nanoparticles, were estimated. It was found that while dielectric constant is an increasing function of temperature, it decreases with increasing frequency. [2] The DC conduction and dielectric behaviour of copper oxide nanoparticles prepared by sol-gel method and sintered at 950 °C were studied in the temperature range of 200–526 K. The formation of single phase monoclinic CuO was confirmed by x-ray diffraction. Wei-Tang Yao, Shu-Hong Yu, Yong Zhou, Jun Jiang, Qing-Song Wu, Lin Zhang, and Jie Jiang, J. Phys. The dielectric constants of the CuO nanoparticles are high at low frequencies, and decrease rapidly when the frequency is increased. The obtained impedance spectra indicated that the grain boundary effects and intergranular activities play a crucial role on the dielectric relaxation processes. Soc 138, 173–177 (1991).
