Structural order in plasmonic super crystals
Plasmons are coherent delocalised electron oscillations that arise when light interacts with metallic nanoparticles. Metallic nanostructures and their ability to confine light at the nanoscale are extensively studied for their use in, for example, energy conversion devices. In particular, plasmonic super crystals (PSCs) – translationally symmetric arrays of metallic nanoparticles – can be used in augmented light-harvesting technologies such as plasmonic solar cells and photocatalysts. Yet, plasmons are fragile, short-living excitations that are highly sensitive to the exact arrangement of matter at the nanoscale. PSCs are prone to multifarious nanomechanical motions that affect their structural stability. Funded by the Marie Skłodowska-Curie Actions programme, the aim of the PLASMMONS project is to further elucidate how nanomechanical motions affect the properties of PSCs.
