Polarization dependence on excess energy.
Degree of circular polarization of the emitted PL as function of excess energy, ΔΕ. Data are derived from spectra where the temperature was held constant and the laser energy was varied, or the laser energy was fixed and the emission energy was varied via a change in temperature. Solid symbols (MoSe2 is red and MoS2 is blue) are our data and open symbols are data from references 8,10,19,20. A graphical definition of excess energy is presented in the inset. Except where noted, error bars are not in excess of the symbol size.
