Hot Electrons and Photochemical effects in Chiral Plasmonic Nanostructures

The generation of energetic (hot) electrons and the photo-heating effect are intrinsic properties of any optically excited plasmonic nanocrystal [1,2]. High-energy hot electrons and phototemperature contribute to kinetic processes observed in plasmonic photodetectors, colloidal nanocrystals, and metastructures [1,2].  This talk will focus on the theory of hot electron generation and also present related applications for plasmonic photochemistry and chiral plasmonic photocatalysis [3,4,5].
