Control of Rolling Direction for Released Strained Wrinkled Nanomembrane

P. Cendula[1], S. Kiravittaya[1], J. Gabel[1], and O.G. Schmidt[1]

[1]Institute for Integrative Nanosciences, Dresden, Germany

Strained wrinkled and flat nanomembranes have different bending properties when they are released from the underlying substrate. This is caused by increased bending rigidity of the wrinkled film in one direction. We provide theoretical and numerical analysis of the directional rolling of wrinkled films, which is important for positioning rolled-up tubes on the short mesa edge during fabrication.
