Abstract

An approach which capitalizes on the growth of instabilities to pattern thin polymeric films was discussed. Experiments that formed concentric rings and theory capable of explaining cylindrically symmetric structures such as rings and rosettes and other cylindrical structures were also presented. It was found that the theory predicts approximately constant ring-to-ring spacings, and growth rates that agree with experiment, constant annular widths. The results show that the perturbation analysis presented is relevant to any system with cylindrical symmetry, for which the radial dependence can be described in terms of Bessel functions.
