Abstract
We discuss the results of simulation and experimental research of processes of origin of quasi-one (island) structures of multicomponent systems based on dislocation growth mechanism. Examination of initial stages of growth of the embryos of the solid phase from the moment of their appearance before the formation of the crystal structure is performed using the model islet of origin and method of cellular automata. As the test materials are considered solid solutions and AlInSbBi AlInGaSbBi the InSb substrate. Based on them the structure obtained with prototypes of quantum dots, the mechanism of formation of which to a certain extent similar to the mechanism of the so-called Ostwald ripening. The paper shows the calculated curves of the induction period of maturation structures.
Keywords: modeling; multi-component systems; quasi-one- dimensional structure; crystal structure; growth mechanisms; quantum dots.
