The efficiency of plasmon-induced hot electron transfer was controlled through systematic variation of the Au tip diameter in CdS-nanorod (NR)/Au nanoparticle (NP) heterostructures.
Significance and Impact
Findings provide a path forward for the rational design of efficient plasmonic hot carrier-based devices to enable a range of important chemical transformations.
– Aberration-corrected scanning transmission electron microscopy (STEM) revealed a clean and abrupt interface between the CdS NR and Au NP.
