Abstract


Localized surface plasmon resonances are central to a multitude of sensing and signal transmission applications. Tuning of the plasmon energy and linewidth is critical to the design of such devices; size, shape, and composition are commonly touted as powerful handles on plasmonic properties. New energy models, describing how kinetic enhancement at crystallographic defects and segregation in alloys influence shape, will be presented. Additionally, experimental results on single particle structure-function correlation on modeled shapes will be described.
