Abstract—The dielectric, structural, and kinetic properties of (GaN)54(SiO2)50 nanoparticles of the following two types are studied using the method of molecular dynamics: particles of GaN covered by a SiO2 layer and particles of  SiO2 with a GaN layer deposited onto it. The absorption and reflection spectra of these nanoparticles are considerably different in the respective frequency ranges 0 ≤ ω ≤ 1500 cm–1 and ω > 700 cm–1. The single-centered functions of the radial distribution of the nanoparticles differ in their peak positions and intensities, including the “tail” part for r > 0.9 nm. The structure of nanoparticles with the SiO2 nucleus is completely tetrahedral, while the nearest six-atom environment is dominant in the structure of a particle with the GaN nucleus. The mobility of gallium atoms in the nanoparticles is lower by two orders than that of other elements constituting them.
