Plasmonics Yields Efficient Electron Transport via Assembly of Shell-Insulated Au Nanoparticles

Plasmonics Yields Efficient Electron Transport via Assembly of Shell-Insulated Au Nanoparticles

Summary: Junctions built from metallic nanoparticles (NPs) can circumvent the diffraction limit and combine molecular/nanoelectronics with plasmonics. However, experimental advances in plasmon-assisted electron transport at the nanoscale have been limited. We construct junctions of a robust, molecul...
