Ultrafast Insights into the Dual-Plasmonic Interaction and Interfacial Charge Separation in the Janus-Type Au-CuxInyS Heterostructure.
Efficient extraction of hot carriers remains a major challenge in plasmonic systems due to their ultrafast relaxation and recombination dynamics. Here, we report the synthesis of Au-CuxInyS (Au-CIS) dual-plasmonic heterostructure nanocrystals (NCs) through a hot-injection method and investigate their ultrafast charge t...
