Non-equilibrium processing can result in different behaviour than that predicted here. The above guidelines were proposed based on equilibrium behaviour, but could be circumvented using non-equilibrium methods to potentially reach the more difficult to obtain orientations (face-on at the vapour interface, side-on at the solid interface). Many common device processing techniques, such as vapour deposition (see refs 80 and 81 for extensive reviews of this method and how processing temperature can influence the orientation), spin coating, or blade coating, are non-equilibrium in nature and so will not necessarily result in the equilibrium structures predicted in this work.
