Аннотация:We have studied the effect of the size of copper oxide nanoparticles on their electrical transport properties. The nanoparticles have been synthesized by vacuum arc deposition and characterized by X-ray diffraction, X-ray photoelectron spectroscopy, and electron microscopy in order to determine their phase composition and size. The results demonstrate that raising the substrate temperature in the deposition process from 300 to 600 K increases the size of the forming nanoparticles from 5.4 to 37.7 nm. The frequency dependences of the electrical conductivity, dielectric permittivity, and dielectric loss tangent of the CuO nanoparticles in the range form 20 Hz to 1 MHz are influenced by their size. In the size range under consideration, distinctions in the dielectric properties of the nanoparticles can be understood in terms of the competing contributions of the competing contributions of the resistive and capacitive components for the particles and grain/particle boundaries.
