The authors have developed a thermodynamics of the solubility of impurities in nanocrystals. The solubility is influenced by the surface energy of the nanocrystal, therefore, with a decrease in its size, the solubility of the impurity decreases, then becomes discrete in it, i.e. a countable number of atoms are dissolved only. In nanocrystals smaller than a certain size, the impurity cannot be dissolved. The calculations apply to silicon nanocrystals in the oxide of this material.
