Processing conditions that favour entropy promote face-on orientation at the solid interface, and side-on at the vapour. In cases where the equilibrium orientation is face-on at the solid interface (which appear to be many), processes such as melt annealing may allow the equilibrium orientation to be obtained, even if deposited through a non-equilibrium method in the opposite orientation. However, when considering high temperatures, care should be taken to ensure that the orientation remains in the entropically favoured orientation as the system is cooled down, which can be achieved by rapid quenching, as the degree of alignment will be a function of temperature.
