At equilibrium, symmetric film systems exhibit a series of
stable films when t = nL 0 (n = 1, 2, 3, 4), whereas antisymmetric
films exhibit a similar series of stable films when t =
(n + 1/2)L 0. It is highly possible to form the island-like
textures for t being not equal to nL 0 and (n + 1/2)L 0.
For symmetric surface energy, first, the domain orientation
was film thickness dependent. In particular, PL gained stability
when t = nL 0, and especially for t < L 0. Second, for neutral
surface energetics, PL was stable for all film thicknesses.
