Abstract
The neutral and interlayer exciton originates from intralayer and interlayer coupling, respectively. Unlike neutral exciton, the interlayer excitons at room temperature are hard to observe and manipulate due to instability. In this work, we show the photoluminescence of WS2 and MoS2 neutral exciton can be improved by oleic acid passivation, allowing trion peaks to be observed at room temperature. More importantly, a 3-fold increase in peak intensity of interlayer excitons is achieved, and the energy peak is blue-shifted 107 meV. Our work paves the way to investigate excitons in two-dimensional transition metal dichalcogenides monolayers and heterostructures at room temperature.
