Periodic nanostructures

The study of periodic nanostructures is one of the leading topics of today’s photonics research. Such structures on the surface of metals, semiconductors, dielectrics or polymers can generate new material properties with very special electrical or mechanical characteristics. Depending on the specific material parameters and the morphology of the structures, new devices like micro-lasers, optical nano-switches, optical storage devices, bio-sensors or anti-fraud features can be realized. Furthermore, surface textures can be used to improve the tribological properties of special tools, for the reduction of reflection losses or as decoration elements for the refinement of precious goods.
