Special Issue Information

Dear Colleagues,

The aim of this Special Issue is the theory, modeling and computer simulations phase separation and encapsulation processes in growing compound thin films taking place during deposition by various methods such as physical and chemical vapor deposition, magnetron sputtering, ion beam assisted deposition, electron beam evaporation and many other methods. Other treatments of compound materials leading to phase separations and encapsulations processes also are in the field of interest. The compound thin film morphology, phase crystalline structure and other structural properties are determined by applied deposition method and it is very important to understand the mechanisms and dynamics of elementary processes taking place during film deposition (adsorption and desorption at non-equilibrium thermodynamic conditions, surface and bulk diffusion, surface chemical reactions at external activation by particle beams (ions, electrons, photons of all electromagnetic spectra), coalescence (considering different mechanisms, activation by external particle beams), clustering, layering, encapsulation, etc.). The deep understanding of elementary processes, their dynamics and mechanisms at different deposition methods allows controlling various physical, chemical and structural properties of films. Despite the huge progress made in theory, mathematical modeling and computer simulation of thin film growth there are still many unanswered questions, especially concerning deposition and growth of multicomponent and compound thin films and coatings, particularly related with phase separation and encapsulation mechanisms. We warmly invite researchers to submit their contributions, both original research articles and review papers, to this Special Issue related with theory, mathematical modeling and computer simulations analyzing kinetics and mechanisms of elementary processes taking place during deposition of compound and multicomponent thin films.

In this study, we applied a mathematical model to explore the mechanism and factors leading to phase separation and the formation of branching structures with nanocolumns extending from larger clusters formed on the substrate of a grown film. The mathematical model simulated the growth of a thin film over time by using partial differential equations, including the processes of adsorption, phase separation, and diffusion due to the curvature of the thin film surface. The modeling results revealed the possible mechanism that could lead to the formation of the described branching structures. That mechanism can be divided into two main steps. The first step is the growth of a relatively large cluster (of a component that makes up the branching phase) on the substrate during the initial growth stages. The second step is the division process of that large cluster into smaller clusters in the later growth stages. The model parameters influencing the growth conditions that lead to the formation mechanism of the branching structures were determined, and their influences on the phase structure were analyzed.
