Paper Abstract

In the work, the density of energy states in the valence band of metallic phase nanograins spherical shape with diameters from 1 to 50 nm was calculated. It was found that the energy distances between neighboring energy states in the valence band of metallic phase nanograins are from 0.1 to 2·10-6 eV for the above-mentioned diameter range. There are many orders larger distance, than characteristic for macroscopic-sized metal, the value of which is approximately 10-22 eV. The calculations show that in nanocomposites consisting of metallic phase nanograins with dimensions below 20 nm placed in a dielectric matrix with high resistivity, there is no characteristic for the macroscopic dimensions band conductivity at low temperatures. The results of the calculation of the distance between neighboring energetic states in the valence band of metallic phase nanograins are consistent with the values obtained experimentally.
