Implication

Experimental study demonstrates tunable photoluminescence in monolayer molybdenum disulfide via chemical doping, indicating an effective approach to modulate two-dimensional semiconductors.

Key Points

To investigate the modulation of photoluminescence intensity and optical properties in monolayer MoS2 through chemical doping.
Treated monolayer MoS2 with solution-based p-type and n-type chemical dopants.
Evaluated optical emission and photoluminescence intensity changes resulting from carrier extraction and injection.
Adsorption of p-type dopants with high electron affinity substantially enhanced photoluminescence intensity in monolayer MoS2.
Adsorption of n-type dopants decreased photoluminescence intensity.
Modulation of photoluminescence was driven by transitions between exciton and trion states dependent on carrier density.
