Figure 2

Time- and excitation-energy-resolved Kerr rotation measurements data in the energy range of (a) the A exciton resonance and (b) the B exciton resonance. The lower panels depict the Kerr rotation angle at a fixed time delay after pulsed excitation. Here the solid red lines indicate the fits to the data, while the blue dashed lines mark the energetic positions of trions and excitons. In the lower left panel, the black dashed lines indicate the contributions of the three resonances considered in the fit.
