We investigate self-organized wrinkling in thin film systems consisting of a molecular glass and a solid cladding, e.g. silicon nitride or aluminium. Upon thermal or phototreatment, well-ordered periodic surface structures evolve which result from stress relaxation in the bilayer system.
In these systems, we investigate the fundamental relationship between material parameters and pattern size and dynamics, and explore applications of the process in device patterning.
