Pattern formation induced by wrinkling is a very common phenomenon exhibited in soft-matter substrates. In all these systems, wrinkles develop in the presence of compressively stressed thin films lying on compliant substrates. Here, the controlled growth of self-organized nanopatterns exploiting a wrinkling instability on a solid-state...

Polydimethylsiloxane (PDMS) templates are nanopatterned over large areas to form uniaxial wrinkles by air plasma treatment on prestretched samples. Ripple-like structures with tunable height/width aspect ratio are so achieved. The anisotropic uniaxial PDMS modulations represent an ideal platform for the confinement of plasmonic nanowire (NW)...
