...Tongay et al.(216) have shown that the light emission efficiency in 2D TMDs (MoS2, MoSe2 andWSe2) is largely modulated by charge transfer with physically adsorbed electronegative gaseous mol-...

...Tongay et al.216 have shown that the light emission efficiency in 2D TMDs (MoS2, MoSe2 andWSe2) is largely modulated by charge transfer with physically adsorbed electronegative gaseous molecules including O2 and H2O, and over a 100-fold modulation in the efficiency was achieved, while inert gases have exhibited a negligible effect....

...The behavior of recombination rates in Figure 3d is consistent with the recent report by Mak et al.10 that at low temperature the X0 emission intensity is gate voltage dependent, while that of X− is mostly gate voltage independent....
