Plasmonic Au/TiO2-dumbbell-on-film nanocavities for high-efficiency hot-carrier generation and extraction

Not Accessible

Your library or personal account may give you access

Abstract

Au/TiO2 dumbbell assembled on Au film optically establish plasmonic nanocavities, resulting in strong near-field enhancement and confinement and eventually contributing to the improved photocurrent, IPCE and decomposition rate.
