Peculiarities of Formation of Clathrate and Percolation Structures in Model Systems C60 - Bi and Bi -Sb

EasyChair Preprint 8650

Abstract

The processes and conditions of formation of materials with specific structure of impurity subsystem have been investigated on the basis of model systems C₆₀ - Bi and Bi-Sb. It is established that in classical Bi-Sb system, traditionally characterized as a system of continuous solid solutions, at low concentrations of impurity, atypical structures are formed, characterized by the formation of impurity percolation channels, and thus by the formation of peculiar composite of matrix of basic component and three-dimensional impurity frame. By the example of the C₆₀ - Bi system it is shown that the formation of clathrate structures, in which the impurity sub-system forms its own sub-lattice, not inherent to the given substance in pure form, is most probable under the conditions of ion implantation of the impurity in the preformed fullerite matrix. While under the conditions of joint condensation of the components the condensation stimulated diffusion processes lead to the formation of a two-phase metal fullerene composite.
