Nanostructured Surfaces for NanoPlasmonic Devices

Nanostructured Plasmonic surfaces can be generated by both top-down and bottom-up approaches.

For the bottom-up approach, we use gold nanoparticles to nanostructure planar surfaces and engineer plasmonics substrates. We investigated the assembly of gold nanoparticles (AuNPs) on various substrates such as gold and silicon with two objectives: (i) understanding the factors governing the interaction and (ii) achieving nanoparticles layers are stable and reliable, which paves the way for their use as nanostructured plasmonic platforms for multiple applications.

The top-down approach is also investigated using clean rooms and electron lithography in collaboration with French and European Labs (INSP, Paris and AIT, Vienna).
