Electronic structure of semiconductor nanoparticles in one-component and mixed systems

The distribution of electron density along the radius of nanoparticles in one- and two-component semiconductor systems at different temperatures and radii of nanoparticles has been obtained taking into account physicochemical processes on their surface. The influence of surface modification of In2O3 nanoparticles by CeO2 nanoclusters in changing the distribution of conduction electrons and the magnitude of the electrostatic field in the nanoparticle volume is demonstrated. The role of these distributions in various physical and chemical phenomena involving semiconductor nanoparticles is discussed.
