The influence of surface modification of In<sub>2</sub>O<sub>3</sub> nanoparticles by CeO<sub>2</sub> 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.</p></abstract><trans-abstract xml:lang="ru"><p>Получено распределение электронной плотности по радиусу наночастицы в одно- и двухкомпонентных полупроводниковых системах при различных температурах и радиусах наночастиц с учетом физико-химических процессов на их поверхности. Продемонстрировано влияние модификации поверхности наночастиц In<sub>2</sub>O<sub>3</sub> наноразмерными кластерами CeO<sub>2</sub> в изменении распределения электронов проводимости и величины электростатического поля в объеме наночастиц.
