WebThe film growth is controlled by the interplay of thermodynamics and kinetics. The general trends in film growth are understood within the thermodynamic approach in terms of the relative surface and interface energies. On the other hand, film growth is a non-equilibrium kinetic process, in which the rate-limiting steps affect the net growth mode.
