Abstract

A model for phase separation two components during a thin film deposition is presented and analyzed in this work. The model includes the processes of adsorption and phase separation. The process of phases separation is described using Cahn- Hilliard equation. Calculations were performed using different approximations (four and six degree polynomials) of free energy of a homogenous system. The formations of columnar, granular-like or mixed patterns are shown by numerical simulations of the presented model. That depends on concentration of the constituent components and approximation of free energy used. [ABSTRACT FROM AUTHOR]
