Abstract
We demonstrate a general feature of organic films between a substrate and a deformable claddinglayer: the capability of forming periodic structures by heating above the glass transition temperatureof the organic film. This patterning process by self-organization is caused by the interplay ofdispersion interactions and mechanical stress which leads to spinodal deformation. The dynamicevolution of the structures was investigated by time-resolved light diffraction. By prepatterning thesubstrate, the direction of the waves can be controlled.
