Controlling plasmon-exciton interactions through photothermal reshaping

We investigated the plasmon-exciton interactions in an individual gold nanorod (GNR) with monolayer MoS2 at room temperature with the single-particle spectroscopy technique. To control the plasmon-exciton interaction, we tuned the local surface plasmon resonance of an individual GNR in-situ by emplo...
