In Situ Mapping of Pressure-Induced Exciton Traps in Suspended MoS <sub>2</sub> Monolayers Using Fabry–Perot Interference
We demonstrate the in situ readout of the spatial profile of suspended MoS2 monolayers hosted on substrates with nanostructured holes. As the profiles are spatially bent, the suspended MoS2 monolayers act as exciton traps with a tunable luminescence intensity and energy. The tunability is realized by controlling the environmental pressure on the monolayers, which allows one to control hundreds of suspended MoS2 monolayers on a single substrate. The in situ readout is based on Fabry-Perot interferences and a model of the corresponding reflectance contrast maps of the investigated monolayers.
