Electrical Properties of Copper Oxide Nanoparticles

Copper Oxide (CuO) nanoparticles were synthesized by the wet chemical method. The crystal structure and grain size of the particles were determined, using X-ray diffraction (XRD). The particle size and morphology were studied using the scanning electron microscope (SEM). The dielectric properties of CuO nanoparticles were carried out at different temperatures. The variation of the dielectric constant and dielectric loss were studied. The dielectric constants of the CuO nanoparticles are high at low frequencies, and decrease rapidly when the frequency is increased. Further, electronic properties like valence electron plasma energy, Penn gap, Fermi energy and electronic polarizability of the CuO nanoparticles, were estimated.
