Theory of Phase Transformations in the Mechanics of Solids and Its Applications for Description of Fracture,Formation of Nanostructures and Thin Semiconductor Films Growth

摘要

The brief review of the current state of the theory of first-order phase transitions is given. The basic processes of nucleation and evolution of nanostructure ensembles on crystal surfaces are considered. The general equations describing nanoparticle size distribution, evolution of their average radius and density are deduced. The influence of mechanical pressure on nucleation and property of quantum dots and nanopores is considered. The equations describing new phase nucleation under condition of mechanical pressure caused by distinction in density of an old and new phase are resulted. The kinetic theory of micropore nucleation in solids under loading is described. The kinetic criterion is received of nucleation of micropores and microcracks in fragile solids under the influence of stretching pressure.
