In this study, we investigated the intertwined mechanism of each plasmon-exciton couplings in monolayer molybdenum disulfide (MoS₂) and plasmonic hybrid structure. The results of absorption, simulation, electrostatics, and emission spectra show that interaction between photoexcited carrier and exciton modes are successfully coupled by energy transfer and exciton recombination processes. Especially, neutral exciton, trion, and biexciton can be selectively enhanced by designing the plasmonic hybrid platform. All of these results imply that there is another degree of freedom to control the individual enhancement of each exciton mode in the develoScientific reportsPlasmon-exciton couplings in the MoS₂/AuNP plasmonic hybrid structure.PMC9789063200172142020M3A7B40249252021M3H4A4079146Kim HHan GHJeong MSIm JHaddadnezhad MPark SChoi SPark WPark JYAhn JSYoo SNam KPark DfalsePlasmon-exciton couplings in the MoS₂/AuNP plasmonic hybrid structure.The understanding and engineering of the plasmon-exciton coupling are necessary to control the innovative optoelectronic device platform.
