Plasmonics is an emerging field in which metallic structures are used to guide light or to enhance interactions between light and materials placed in their vicinity (field enhancement). With the continual trend towards smaller dimensions of plasmonic structures, optical techniques are no longer capable of characterising the spatial distribution of field enhancement due to the plasmonic nano-structures. Electron energy-loss spectroscopy (EELS) can be used as an alternative technique for studying the plasmonic response of structures with sub-nanometre spatial resolution. This project focuses on using EELS to study the evolution of field enhancement near metallic nano-particles. The results will yield information that will enhance our understanding of plasmonics and help develop more accurate theories.
