Abstract: Phase equilibria in Six – Ge1-x nanoparticles of various compositions within the two-phase region between the liquidus and solidus temperatures have been simulated by using methods of the equilibrium chemical thermodynamics. It has been shown that the equilibrium compositions of liquid and solid phases dramatically depend on the initial composition of a nanoparticle and the character of such dependences is different at different temperatures. Reducing the size of a nanoparticle is accompanied by narrowing the temperature interval of the two-phase region.
Keywords: nanostructuring, nanoparticles, germanium, silicon, melting, liquidus, solidus.
