It has been demonstrated using the computer simulation that, in Sy 1 ⎯ y solid solutions with square and hexagonal lattices, the appearance of a correlation between the S atoms and vacancies in the first coordination shell leads to the appearance of correlations in the second and subsequent coordination shells. An increase in the radius of the coordination shell leads to a decrease in the magnitude of induced correlations, and the correlations completely decay in the ninth coordination shell. The functional dependence between the correlation in the first coordination shell and the induced correlations in the subse quent coordination shells has been established for different compositions of the Sy 1 – y solid solution. The results of the simulation can be used to refine the crystal structure of nanocrystalline films and particles of lead sulfide Доп.точки доступа: Rempel, A. A.; Ремпель Андрей Андреевич
