Computer simulation for formation of critical spaces in II-VI solid solutions

Predicting of optimal properties of II-VI materials is an important task in solving the problems of micro- and nanoelectronics. Multicomponent solid solutions based on such semiconductors are promising for modern optoelectronics, for they allow creating devices that operate in a wide spectral range. However, under certain conditions multicomponent solid solutions lose their thermodynamic stability, and thus the properties of the devices based on such materials degrade. Modern methods of computer simulation are used to analyze processes of formation of self-organizing ordered structures. The authors use differential topological approach to obtaining multicomponent phase diagrams taking into account the possibility of existence of bifurcation spaces, critical spaces, and spaces of phase coexistence of different orders.
