| Abstract Scope |
Ultrafast-laser irradiated surface is a typical paragon of a self-organizing system, which emerges and organizes complex micropatterns and even nanopatterns. A spectacular manifestation of dissipative structures consists of different types of randomly and periodically distributed nanostructures that arise from a homogeneous metal surface. The formation of nanopeaks, nanobumps, nanohumps and nanocavities patterns with 20–80 nm transverse size unit and up to 100 nm height are reported under femtosecond laser irradiation with a regulated energy dose. We shed the light on the originality of the nanopeaks, having an exceptional aspect ratio. They are primarily generated on the crests grown between the convective cells formed by the very first pulses. The production of these distinct nanostructures can enable unique surface functionalizations toward the control of mechanical, biomedical, optical, or chemical surface properties on a nanometric scale. Here, we focus on the potential role of self organized nanostructures for energy storage application. |
