The range of variations in the triple correlation is determined as a function of the composition of the AyB1 –y solid solution and the value of the pair correlation. It is assumed that periodically ordered planar hexagonal and square island nanostructures can be considered as solid solutions A1/4 3/4with vacancy sites and sites occupied by nanoparticles A . In this case, an ordered distribution of nanoparticles over the planar-lattice sites occurs because the nearest neighbor pair correlation is negative and has a maximum magnitude Доп.точки доступа: Гусев Александр Иванович
