Estimation of the Effect of Spinodal Decomposition in Thin Films

The deposition of thin films has found many applications in Academia and Industry. The technology is capable of producing extremely thin films unattainable by the usual mechanical coating methods. The temperature regime where precipitation from vapour to solid begins is an important factor since it decides the type of ambient cooling or heating required. In this work, a model is applied to describe deposition, and the thermal regions where solutions are possible are analyzed by simulation including the 4th order derivatives for spinodal decomposition. The effect of spinodal transformation is analyzed. Applications are made to some commercially viable compounds.
