Surface Crinkling of Strained Diblock Copolymer Smectic Thin Films on Striped Substrates
We study theoretically the problem of a thin symmetric diblock copolymer melt or other smectic film placed on a chemically heterogeneous striped substrate. Recent experimental and numerical studies of this system have shown that the lamellae often align perpendicular to the substrate but, that they also tend to crinkle or undulate. Here we show how this rippling can be understood as an instability caused by the intrinsic strain in the system. This instability is closely related to the classical...[Show more]
