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)...

Self-organized wrinkled templates are homogeneously fabricated over a large area (cm2) glass substrates by defocused ion beam irradiation, demonstrating the capability to induce and modify at will the out-of-plane tilt of the nanofacets with selected slope. We identify a region of morphological instability which leads to faceting for incidence...

Multifunctional flexible Au electrodes based on one-dimensional (1D) arrays of plasmonic gratings are nanofabricated over large areas with an engineered variant of laser interference lithography optimized for low-cost transparent templates. Au nanostripe (NS) arrays achieve sheet resistance in the order of 20 Ohm/square on large areas (∼ cm2)...
