Plasmonic Nanocrystals and Hybrids with Complex Shapes for Hot Electron Generation and Photochemistry

The generation of energetic (hot) electrons and the photoheating are intrinsic properties of any optically excited plasmonic nanocrystal [1,2]. In addition, high-energy hot electrons and phototemperature contribute to the kinetic processes observed in colloidal nanocrystals, metal-semiconductor hybrids, plasmonic Schottky photodetectors, and metastructures [1,2]. In this talk, we will focus on the theory of hot electron injection and present related applications for plasmonic photochemistry and plasmonic photocatalysis [3,4,5,6]. <br/> <br/> <br/>[1] L.
