Tuning photoluminescence of single-layer MoS2 using H2O2
Enhancing photoluminescence (PL) of single-layer (1L) MoS 2 is critical to its application as the thinnest light-emitting material. In this report, we show that the PL intensity of 1L-MoS 2 can be enhanced by 8 times using physisorption of H 2 O 2 molecules as p-type dopants. By using toluene to for...
