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...

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...

Flat-optics microfluidic sensors based on one-dimensional Au nanostripe lattices are homogeneously fabricated over a large area (cm^2), demonstrating a cost-effective approach able to combine scalable functionalization of transparent templates, fast and compact optical detection, and competitive refractive index sensing capabilities. Laser...

Highly porous Germanium surfaces with uniformly distributed columnar nanovoid structures are fabricated over a large area (wafer scale) by large fluence Sn+ irradiation through a thin silicon nitride layer. The latter represents a one-step highly reproducible approach with no material loss to strongly increase photon harvesting into a...

High density gold nanostructures are grown by thermal deposition on flat and nanostructured polymeric templates by exploiting the extraordinarily low wettability of Au on polydimethylsiloxane (PDMS). Undulated PDMS templates are fabricated by replica molding process (REM) on "masters" prepared by defocused Ion Beam Sputtering (IBS). Closely...
